Question

How do you find the GCF of `15r^2t, 35t^2, 70rt`?

Answer 1

See the solution process below:

Explanation:

We can factor each of these terms as:

`15r^2t = 3 xx color(red)(5) xx r xx r xx color(red)(t)`

`35t^2 = color(red)(5) xx 7 xx color(red)(t) xx t`

`70rt = 2 xx color(red)(5) xx 7 xx r xx color(red)(t)`

Therefore the Greatest Common Factor is: `color(red)(5t)`
