definition

If an integer is divisible by another integer, then the second integer is the divisor of the first integer. The divisor is finite, and the greatest common divisor is generally used.

for instance

The divisors of 6 are: 1, 2, 3, 6.

The divisors of 10 are: 1, 2,5, 10.

The divisors of 15 are: 1, 3,5, 15.

………………

Note: The divisor of a number includes 1 and itself.

The quotient (b≠0) obtained by dividing the integer A by the integer B is exactly an integer with no remainder, so we say that A can be divisible by B or B can be divisible by A. A is a multiple of B, and B is a divisor or factor of A. Dividers and multiples depend on each other, so we can't say that a number is a divisor or multiple.
