Multiples and factors are the knowledge points in what grade of primary school?

The Sujiao version and the Renjiao version are the second volume of knowledge in the fifth grade, Figure 1 is the table of contents of the Sujiao version, and the content of the third unit is factors and multiples; Figure 2 is the People's Education Edition, the content of the second unit.

Multiples and factors are the knowledge of the fifth grade of primary school, the number of factors of a number is limited, the smallest is 1, and the largest is itself.

The number of multiples of a number is infinite, and the smallest multiple is itself, and there is no maximum.

It is the content of the fifth grade of elementary school. 1. Factor, which is a divisor, is a mathematical noun. Definitions:

The quotient of the integer a divided by the integer b(b≠0) is exactly an integer without a remainder, so we say that b is a factor of a. 0 is not a factor of 0. 2. Multiples, an integer can be divisible by another integer, and this integer is a multiplier of another integer.

For example, 15 is divisible by 3 or 5, so 15 is a multiple of 3 and a multiple of 5.

1. Factor, or become a divisor, a mathematical term. Definition: The quotient of the integer a divided by the integer b(b≠0) is exactly an integer without a remainder, and we say that b is the factor of a. 0 is not a factor of 0.

Multiples and factors should be knowledge in the sixth grade of primary school. Multiples are how many times a number is another number.

When I was in the fourth grade, I guess so.

Factor definition: The quotient of integer a divided by the integer b(b≠0) is exactly an integer and there is no remainder, we say that b is the factor of a. 0 is not a factor of 0.

Definition of multiples: An integer can be divisible by another integer, then this integer is a multiple of another integer.

Multiples and factors are mathematics knowledge in the fifth grade of primary school, and multiples and factors are just beginning to be learned in the fifth grade, and the content of this chapter is not difficult to learn.

Any factor, this should be a knowledge point in junior high school, it should not be a knowledge point in primary school, this should be about the first year of junior high school can be learned, and you should be able to know what he has learned.

It is the knowledge point of the fifth grade of primary school.

Knowledge points in the second volume of the fifth grade of primary school.

1. In integer division, if the quotient is an integer and there is no remainder, we say that the dividend is a multiple of the divisor, and the divisor is the factor of the dividend. Factors and multiples are interdependent and cannot exist in isolation.

2. Note: For convenience, when studying factors and multiples, the number we mean is the natural number.

3. Methods of finding factors: multiplication, division; How to find multiples: multiply natural numbers one by one.

4. The minimum factor of a number is 1, and the maximum factor is itself. The smallest multiple of a number is itself, there is no maximum multiple. The number of factors of a number is finite, and the number of multiples of a number is infinite.

The maximum factor and the minimum multiple of a number are equal and are both in itself.

5. Factor or multiple of the body or the factor of the greatest factor of the body and the smallest multiple of the body. The larger a number, the more factors it has, and the smaller a number, the fewer its factors. This statement is false.

These problems are because none of us can do it: it happens from different places to ......These are not alone. Are you real? Can't extricate yourself

1. Like ......Such numbers are natural.

2. Like and Oak ......Such a number is an integer.

3. The relationship between integers and natural numbers: integers include natural numbers.

4. Multiples and factors: For example, 4 5 = 20, 20 is a multiple of 4 and 5, 4 and 5 are the factors of 20, and multiples and factors are interdependent.

5. Find multiples: start from 1 times to find in an orderly manner.

6. The characteristics of a number multiple: The number of multiples of a number is unlimited; The smallest multiplier is itself; There are no multiples.

7. Find the factor: find the factor of a number, and find it better to find it in an orderly one-to-one pair.

8. The characteristics of a number factor: The number of factors of a number is limited; The smallest factor is 1; The factor is itself.

Characteristics of multiples: the number of the single digit is a multiple of 2.

10. Odd and even numbers: Numbers that are multiples of 2 are called even numbers, and numbers that are not multiples of 2 are called odd numbers. Natural numbers can be divided into two categories: odd and even.

Characteristics of multiples of : the single digit is 0 or the number of 5 is a multiple of 5.

Characteristics of multiples: The sum of the numbers on each digit is a multiple of 3, and this number is a multiple of 3.

13. The characteristics of multiples of both 2 and 5: the number with a single digit is 0. Characteristic of being both a multiple of 2 and a multiple of 3:

The single digit is the number of ; The sum of the digits on each digit is a multiple of 3 and is a multiple of 5: a number with a single digit of 0 or 5; The sum of the digits is a multiple of 3, which is a multiple of 2 and a multiple of 3, and a multiple of 5: the number of the single digit is 0; The sum of the digits is a multiple of 3 and a multiple of 9

The sum of the digits is a multiple of 9, and this number is a multiple of 9.

14. Prime number: A number has only 1 and its own two factors, this number is called a prime number. The smallest prime number is 2, which is an even number in the prime number. Prime numbers within 100:

15. Composite number: A number has other factors besides 1 and itself, and this number is called a composite number. 1 is neither prime nor composite, and the smallest composite number is 4

16. According to the number of factors of a number, natural numbers can be divided into three categories.

The knowledge points of factors and multiples are as follows:1. The characteristics of multiples: the number of multiples of a number is unlimited, and the smallest multiple is itself.

Characteristics of multiples: The sum of the numbers on the sides of a number is a multiple of 3, and this number is a multiple of 3.

3. Greatest common factor: the common factor of several numbers, which is called the common factor of these numbers. The largest of these is called the greatest common factor of these numbers.

4. Factors and multiples are interdependent. For example: 12 2=6, we say that 12 is a multiple of 2 and 2 is a factor of 12.

5. In integers, the number of multiples of 2 is called even, and the number that is not a multiple of 2 is called odd. 0 is the smallest even number; 1 is the smallest odd number.
