*FAN/MEDAL* Find the greatest common factor of the numbers. 120, 960 Please show all of your work, and all of the factors.

OpenStudy (faiqraees):

can you prime factorize both numbers

OpenStudy (anonymous):

Um, yes.

OpenStudy (anonymous):

But this isn't prime factorization, this is GCF.

OpenStudy (faiqraees):

yeah still they also require it

OpenStudy (anonymous):

No, they don't... "Find the greatest common factor of the two numbers." We already learned Prime Factorization.

OpenStudy (faiqraees):

do it I will tell you what to do next

OpenStudy (anonymous):

Okay, fine. One second.

OpenStudy (anonymous):

120 = 2, 2, 2, 3, 5 960 = 2, 2, 2, 2, 2, 2, 3, 5

OpenStudy (anonymous):

What next?

OpenStudy (anonymous):

What's**

OpenStudy (anonymous):

Do I really have to do prime factorization? I'm just listing factors and I need help doing this.

OpenStudy (anonymous):

that*

OpenStudy (faiqraees):

okay well now can you convert them in squared and cubed forms

OpenStudy (anonymous):

Bruh.. listen, I'm just listing factors here.

OpenStudy (jingle535):

Jam for this problem you don't, but its a general strategy for others. For this you can do a simple check and divide the bigger number by the smaller number to see if the smaller number is the GCF of them.

OpenStudy (faiqraees):

120 = 2, 2, 2, 3, 5 960 = 2, 2, 2, 2, 2, 2, 3, 5 What are the common factors here???

OpenStudy (jingle535):

To find the GCF you list the factors of both numbers and pick the biggest one of both, Faiq is telling you another way so you don't have to do as much work.

OpenStudy (jingle535):

The thing is, you can do a simple check and divide the bigger number by the smaller number and if the answer is not a decimal then the GCF of the two numbers is the smaller number.
