Multiples of 20 have ......
Just multiply 20 by any natural number.
He's a multiple of 20.
Therefore, the minimum multiple of 20 is 20, and there is no maximum multiple of 20.
Multiples of 2. At the end of a number is an even number (0,2,4,6,8), and this number is a multiple of 2.
For example, the end of 6 is a multiple of 2. 3776÷2=1888。
Multiples of 3. The sum of the digits of a number is a multiple of 3, and this number is a multiple of 3.
4926。(4+9+2+6) 3=7, which is a multiple of 3. 4926÷3=1642。
Multiples of 4. The last two digits of a number are multiples of 4, and this number is a multiple of 4.
is a multiple of 4. 2356÷4=589。
Multiples of 5. If a number ends with 0 or 5, this number is a multiple of 5.
at the end of . Multiples of 6. As long as a number is divisible by both 2 and 3, then the number is divisible by 6.

Anonymous users2024-02-0620 is a multiple of 20 is right, and 20 is 1 times of 20.
An integer can be divisible by another integer, which is a multiple of another integer. For example, 15 is divisible by 3 or 5, so 15 is a multiple of 3 and a multiple of 5.
The quotient obtained by dividing one number by another, e.g. a b = c, that is, a is a multiple of b. For example, if a b=c, it can be said that a is c times that of b.
Multiples of 7:
If the single digit of an integer is truncated, and then 2 times the single digit is subtracted from the remaining number, if the difference is a multiple of 7, the original number is divisible by 7. If the difference is too large or it is not easy to see whether it is a multiple of 7, the above process of truncating, multiplying, subtracting, and checking the difference will be carried out until it can be clearly determined.
For example, the process of determining whether 133 is a multiple of 7 is as follows: 13-3 2=7, so 133 is a multiple of 7; Another example is the process of determining whether 6139 is a multiple of 7 as follows: 613-9 2=595, 59-5 2=49, so 6139 is a multiple of 7, and so on.

Anonymous users2024-02-03In order to find out the multiples between 21 and 40, the numbers can be checked one by one to see if they can be ,...Divisible by any one of 40. Alternatively, mathematical methods can be used to simplify the process.
The least common multiple between 21 and 40 is 840, so you only need to find the factor of 840 and check whether they are between 21 and 40 to find out the multiple between 21 and 40. According to the method of decomposition of the quality nano factor, 840 can be decomposed into $2 3 3 5 7$. Therefore, its factors are:
Then, from these factors, multiples between 21 and 40 are screened out, i.e.:
Therefore, the multiples between 21 and 40 are and 40.

How much is the maximum? How many times?
If you don't have a boundary, then we are here all year round to tell you that there is no end to it, and there are tens of millions of cracked silver skins in multiples of each number.

Anonymous users2024-01-31Your question is very troublesome. You don't give a range, and the numbers are infinite. So they have an infinite number of dead and spoiled fibers, so there is no way. With imitation.

Anonymous users2024-01-30The doubling of 20 is late
Doubling the size of the slow ear is to increase which side is doubled, the original 2 times.

Anonymous users2024-01-29There are infinite multiples of 2 and infinite multiples of 20, so they cannot be compared
So the answer is:

Anonymous users2024-01-28Wrong. It should be calculated as such. (40-20) 20=1, i.e. 40 is twice as much as 20.

Anonymous users2024-01-27Answer: According to the meaning of the topic, it can be seen that it is wrong.
Because (40-20) 20
40 is more than 20 times more than 1 time to serve the right, so it's wrong.
