The common factors of 12 and 28 are 1, 2 and 4
Just 1
The common factors of 12, 20 and 36 are: 1, 2, and 4
The common factors of 12, 20, and 24 are: 1, 2, and 4The GCF is 4.
The GCF of 12 and 20 is 4.The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 20 are 1, 2, 4, 5, 10, and 20.The factors they have in common are 1, 2, and 4. Therefore, 4 is the greatest common factor.The greatest common factor can also be determined from the prime factors by multiplying the common prime factors together.The prime factors of 12 are 2, 2, and 3.The prime factors of 20 are 2, 2, and 5.The common prime factors are 2 and 2, so the greatest common factor is 2 x 2 = 4.The greatest common factor of 12 and 20 is 4
Factors of 12 are 1, 2, 3, 4, 6, and 12 Factors of 20 are 1, 2, 4, 5, 10, and 20 Common factors would be 1, 2, and 4.
The common factors are: 1, 2, 4
The factors of 12 are 1, 2, 3, 4, 6, and 12The factors of 18 are 1, 2, 3, 6, 9, and 18The factors of 20 are 1, 2, 4, 5, 10, and 20The common factors of 12, 18 and 20 are 1 and 2The common factors of 12 and 18 are 1, 2, 3, and 6The common factors of 12 and 20 are 1, 2, and 4The common factors of 18 and 20 are 1 and 2The total number of factors for 12, 18 and 20 are all the same (6).
The GCF of 8, 12, and 20 is 4 One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 8 are 1, 2, 4, and 8. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 20 are 1, 2, 4, 5, 10, and 20. The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.
Factors of 12 are 1, 2, 3, 4, 6, and 12 Factors of 20 are 1, 2, 4, 5, 10, and 20 For a Venn diagram showing the factors of 12 and 20, label 1, 2, and 4 as the common factors of 12 and 20 and place them in the in the overlap area. Label and place the remaining factors of 12 (3, 6, and 12) in one of the end nodes and the remaining factors of 20 (5, 10, and 20) in the other end node.
