What is the greatest common factor of 24s^3, 12s^4, and 18s

You have to find the number that can be divided into 24,12 and 18. That number would be six. Now we need to look at the exponents s^3 s^4 and s you cant only take out 1 s because 18s doesnt have more than 1 so the final answer would be 6s

6s. 2 and 3 divide into all these numbers but six is the greatest number that all

Divide into and they all have one s at least.
