Find the GCF of 12, 16, and 20

4

Step-by-step explanation:

The greatest common factor is the largest number that is a shared factor of all 3 numbers (the greatest number they can all divide into). To find the GCF, we can list all the factors of the 3 numbers and then find the largest one that is common to all three sets.

Factors of 12 are: 1,2,3,4,6,12

Factors of 16 are: 1,2,4,8,16

Factors of 20 are: 1,2,4,5,10,20

We can see that 1,2 and 4 are the numbers common to all three sets but 4 is the largest so 4 is our greatest common factor.

Hope this helped!

Step-by-step explanation:

4 is the GCF od 12, 16 and 20

its a little blurry tbh

step-by-step explanation:

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
