List them.
Example: 30 and 42
1, 2, 3, 5, 6, 10, 15, 30
1, 2, 3, 6, 7, 14, 21, 42
The numbers on both lists are the common factors: 1, 2, 3 and 6.

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.
How do you solve the greatest common factor for 21 24 and 27?
List the factors. The factors of 21 are: 1, 3, 7, 21 The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24 The factors of 27 are: 1, 3, 9, 27 The common factors are: 1, 3 The Greatest Common Factor: GCF = 3
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 is the difference between common factors and greatest common factors?
The greatest common factor is the largest of the common factors.
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.
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!;)
What are 2 methods to solve a gcf problem?
Two methods to solve a greatest common factor (GCF) problem are the prime factorization method and the listing method. In the prime factorization method, you find the prime factors of each number and determine the common factors. The GCF is the product of the common prime factors. In the listing method, you list the factors of each number and find the common factors. The GCF is the greatest common factor from the common factors list.
How do you solve greatest common divisor?
1. Reduce all numbers to prime factors 2. Find primes that are common in all numbers 3. Multiply the common primes together
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.
