Question

Write all the factors of the following number.

$90$

Answer 1

A factor of a number is an exact divisor of that number.

Factors of $90$ are

$90=1\times 90$

$90=2\times 45$

$90=3\times 30$

$90=5\times 18$

$90=6\times 15$

$90=9\times 10$

Hence the factors of $90$ are $1,2,3,5,6,9,10,15,18,30,45$ and $90$.
