Question

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

Answer 1

Answer:  First option is correct.

Step-by-step 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

$4\times 4\times s\times s\times s\times t$

Factors of $40s^5$ is given by

$2\times 2\times 2\times 5\times s\times s\times s\times s\times s$

Factors of $68t^2$ is given by

$17\times 2\times 2\times t\times t$

So, GCF ( Greatest common factor) will be

$2\times 2=4$

Hence, First option is correct.

Answer 2

4 is the only factor common among all terms
