The quotient obtained by dividing one number by another. For example, a÷b=c, that is, A is a multiple of B, for example, A÷B=C, it can be said that A is C times that of B.
A number has countless multiples, which means that the set of multiples of a number is infinite.
Note: you can't call a number a multiple alone, you can only say who is a multiple of who.
Extended data:
If one digit of an integer is truncated, subtract twice this digit from the rest. If the difference is a multiple of 7, the original number can be divisible by 7. If the difference is too big or it is not easy to see whether it is a multiple of 7 in mental arithmetic, the above-mentioned "truncation, multiplication, subtraction and difference test" process should be carried out until a clear judgment can be made.
For example, the process of judging whether 133 is a multiple of 7 is as follows: 13-3×2=7, so 133 is a multiple of 7; For another example, the process of judging whether 6 139 is a multiple of 7 is as follows: 6 13-9×2=595, 59-5×2=49, so 6 139 is a multiple of 7, and so on.
If the difference between the sum of odd digits and the sum of even digits of an integer is divisible by 1 1, then this number can be divisible by 1 1. Such as 264,3080 and 95949392, 2+4-6= 1 1×0, 3+8-0 =11,9× 4-(5+.
The multiple test method of 1 1 can also be treated by the "tail-cutting method" of the above-mentioned inspection 7. The only difference in the process is that the multiple is 1 instead of 2.
Separate a number from the unit. If the sum of all separated numbers is a multiple of 1 1, the number is a multiple of1(for example, 3257 1, divided into 3 25 7 1, 3+25+7/kloc-0.
