What are the common factors and greatest common factor?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a factor of 9. 3 is a factor of 15. 3 is a common factor of 9 and 15.
What are the common factors and greatest common factors of 12 and 15?
The common factors are 1 and 3. The greatest of these is 3.
What does greatest common factor means?
It is the lowest common number between to initila numbers.Ex.: GCF of 2,3 & 4 is 122: 2, 4, 6, 8, 10, 12, 14,16, 20...3: 3, 6, 9, 12, 15, 18, 21...4: 4, 8, 12, 16, 20...
What is the greatest common factors of 12 and 32?
The GCF of 12 and 32 is: 4.One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 12 are 1, 2, 3, 4, 6, and 12.The factors of 32 are 1, 2, 4, 8, 16, and 32.The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 12 are 2, 2, and 3.The prime factors of 32 are 2, 2, 2, 2, and 2.The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.
What is the greatest common factor of 12 and 37?
To find the Greatest Common Factor (GCF) of 12 and 37, you could list the factors of each and find the one that is greatest that they have in common. In that case, the factors would be: 12: 1, 2, 3, 5, 6, 12 37: 1, 37 the GCF is 1 In this case, though, you shouldn't have to do that. By looking at the numbers, you should notice that 37 is a Prime Number and has no factors in common with the number 12, except for 1.
