Question

What is the GCF of `45x^2y` and `9x^3`?

Answer 1

GCF is `9x^2`

Explanation:

Factors of `45x^2y` are given by

`45x^2y=color(red)(3xx3)xx5xx color(red)(x xx x) xxy`

and for `9x^3`, we have factors

`9x^3=color(red)(3xx3xx x xx x) xx x`

Common factors are `3xx3xx x xx x` and hence

GCF is `3xx3xx x xx x=9x^2`
