Question

Check whether the first number is the factor of the second number, or not.

$15,60$

Answer 1

We know that A factor of a number is an exact divisor of that number

when we divide the second number by the first number if we get the remainder $0$ we say that the first number is the factor of the second number.

$60÷15=4$

in this case, we get remainder $0$

Hence the first number is the factor of the second number.
