Question

What do you mean by factors?

Answer 1

Define factors:

A factor is a number that divides the given number without leaving any remainder.

Example:

$21=3\times 7$

Here, $21$ is divisible by $3$ and $7$ without leaving any remainder.

Thus, $3$ and $7$ are the factors of $21$.

Hence, a factor is a number that divides another number leaving remainder
