Question

What is the greatest common factor of 24, 36, and 72? A) 9 B) 12 C) 24 D) 18

Answer 1

Answer:

B

Step-by-step explanation:

First prime factorize each number; this means breaking up the number into the product of only prime numbers.

24 = $2^3*3$

36 = $2^2*3^2$

72 = $2^3*3^2$

Looking at these three numbers, we see that the biggest number they share is of the form: $2^2*3$ , where is just 12.

Thus, the answer is B.

Hope this helps!

Answer 2

Answer:B

Step-by-step explanation:

You can find the GCF by seeing if the number is divisible so for 9 24/9 isn’t a integer so no for 12 24 36 and 72 are divisible so it maybe the answer for 24 36/24 isnt a integer for 18 24/18 isn’t a integer
