Answer 1

7

Explanation:

7 goes into each group

21÷7=3

14÷7=2

35÷7=5

Answer 2

Answer: 7

Explanation:

Given : Goodies Gumballs has a bag with 21 pink gumballs, 14 blue gumballs, and 35 white gumballs.

Then, the greatest common factor Goodies can use to divide the gumballs into equal groups will be the greatest common factor (GCF) of 21 , 14 and 35.

Prime of 21 ,14 and 35 will be :-

`21=3*7\\\\14=2*7\\\\35=5*7`

We can see that GCF(21, 14 , 35)=7

Hence, the greatest common factor Goodies can use to divide the gumballs into equal groups =7.
