Answer 3

Let us say you have worked out the factors of two numbers:

Example: Factors of 12 and 30

Factors of 12 are 1, 2, 3, 4, 6 and 12
Factors of 30 are 1, 2, 3, 5, 6, 10, 15 and 30
Then the common factors are those that are found in both lists:

Notice that 1, 2, 3 and 6 appear in both lists?
So, the common factors of 12 and 30 are: 1, 2, 3 and 6
It is a common factor when it is a factor of two or more numbers.
(It is then "common to" those numbers.

Answer 4

now with that in mind ,make a list of the factors.

Answer 5

but what if you can only use one number

Answer 6

as the answer

Answer 7

then in the example I gave you 6 would be the GCF

Answer 8

The "Greatest Common Factor" is the largest of the common factors

Answer 9

so the answer to my question would be 4?

Answer 10

24 :1,3,4,6,8,12 ,24
44:1 44 2 22 4 10
so yes 4 is the GCF

Answer 11

*44 : 1,2,4,10,22,44

Answer 12

A more general way of doing this problem and other problems dealing with big numbers is to write the prime factorization of each number to find the GCF
\[
24 = 2^3\times 3\\
44 = 2^2 \times 11

\]
You can see that \( 2^2=4\) is the GCF

Answer 13

can you help with a few more

Answer 14

I'll try to :)

Answer 15

What is the LCM of 15 and 60

Answer 16

A common multiple is a number that is a multiple of two or more numbers. The common multiples of 3 and 4 are 0, 12, 24, ....
The least common multiple (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.
