Answer 1

10, 20w, 2w, and we are factors of 20w and 40wz

Answer 2

Answer with Step-by-step explanation:

We are given 2 terms

20w and 40wz

We have to find their common factors.

20w=2×2×5×w

40wz=2×2×2×5×w×z

As we can see from the above factorization that,

10=2×5 is common in both

20w=2×2×5×w is common in both

2w=2×w is common in both

w is common in both

Hence, the common factors of 20w and 40wz are:

10,20w,2w and w
