What is the greatest common factor of 8 and 36?
a. 2
b. 4
c. 6
d. 8

The greatest common factor is 4.

Step-by-step explanation:

The easiest way to do this exercise is to make two lists: one with all the factors of the number 8, and another with all the factors of 36. Thus,

Factors of 8 : {1, 2, 4, 8}

Factors of 36: {1, 2, 3, 4, 6, 9, 12, 18, 36}

Then, we found that the common factors are {1, 2, 4}. So, as the larger number in the last list is 4, we conclude that the greatest common factor is 4.

πr^2/2

where r is the radius of the pizza.
