What is the greatest common factor of 24 and 25?
24 and 25 have no common factor, other than one. There can be only one "greatest". There are two ways to solve for the greatest common factor. One way is to solve is to find the common prime factors and multiply them. So 24 = 2*2*2*3 and 25 = 5*5 Since they do not have common prime factors they do not have a GCF. Another way to solve it (just to reassure you) is to list the factors. 1. 24: 1, 2, 3, 4, 6, 8, 12, 24 25: 1, 5, 25 2. Again, you see they don't have a common factor. So technically the greatest common factor is 1.

What is the greatest common factor of 8 and 52?
The greatest common factor of 8 and 52 is 4The factors of 52 are 1, 2, 4, 13, 26, and 52.The factors of 8 are 1, 2, 4, and 8.The greatest common factor is 4.You can also solve it by looking at the prime factors.The prime factors of 52 are 2, 2, and 13.The prime factors of 8 are 2, 2, 2, and 2.The common factors are 2 and 2, so the greatest common factor is 2 x 2 = 4.
What are the common factors of 15 and 24?
3 is the only oneTo solve this question first express 24 and 15 as prime factors:24 = 2 * 2 * 2 * 315 = 5 * 3Immediately it can be seen that the only common factor between the two numbers is 3.1 and 3.
What is the difference between common factors and greatest common factors?
The greatest common factor is the largest of the common factors.
How does finding the common factors or multiples help you solve a problem?
The answer will depend on the problem!
How do you solve fractions in the lowerst terms?
Divide top and bottom by whatever common factors they have.
Why do common multiples and common factors help solve a problem?
yes because it helps me figure out all the prime numbers!;)

How do you solve discrete series by grouping?
You will need to use the distributive law to solve discrete series by grouping. The distributive law is a(b + c) = ab + ac. You will be removing the common factors as you go.
