Multiplication is a mathematical term that refers to the product of a number and an integer.

In other words, for two numbers A and B, if there is an integer n that makes b = na, then B is a multiple of A. If A is not zero, it means that b/a is an integer, and its division can be divisible without remainder. A multiple of 2, also known as an even number. If both a and b are integers and b is a multiple of a, then a is a factor of b, multiplied by = factor multiplied by y.

If both A and B are integers and an integer C is a multiple of A and B, then C is called the common multiple of A and B, and if C is the smallest positive integer satisfying the above conditions, it is called the least common multiple.
