Question

What is the GCF of 16s3t, 40s5, and 68t2? 4 4s3t 8 8s3t

Answer 1

4 is the only factor common among all terms

Answer 2

Answer: First option is correct.

Explanation:

Since we have given that

`16s^3t,40s^5\ and\ 68t^2`

First we write the factors of all of these numbers:

Factors of
`16s^3t` is given by

`4* 4* s* s* s* t`

Factors of
`40s^5` is given by

`2* 2* 2* 5* s* s* s* s* s`

Factors of
`68t^2` is given by

`17* 2* 2* t* t`

So, GCF ( Greatest common factor) will be

`2* 2=4`

Hence, First option is correct.
