Question

Need help with #3.What are the common factors of 20w and 40wz

Answer 1

Answer:

10, 20w, 2w and w

Step-by-step explanation:

Common factors are numbers that can be multiplied by another number to get two or more different numbers.

In this case, we have:

20w and 40wz

Factors of 20w are:

2, 4, 5, 10, 20 and w; or the combination of both: 2w, 4w, 5w, 10w, 20w

Factors of 40wz are:

2,4,5, 8, 10, 20,...etc. and w and z; or the combination of the three.

To find the common factors we have to see which factors are common between the two:

2, 4, 5, 10, 20, w or the combinations:

2w, 4w, 5w, 10w, 20w.

Now we have to select from the options:

10, 20w, 2w and w
