The common factors of 6 and 15 is 1 and 3 that's all
The common factors of 6 and 15 are 1 and 3.
There are no common factors of 15 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common.The factors of 15 are 1, 3, 5, and 15.Examples:The common factors of 6 and 15 are 1 and 3.The common factors of 15 and 90 are 1, 3, 5, and 15.1,5,3, and 15.
The answer to this is 3
1 and 3
The common factors are: 1, 3, 5, 15.
The factors of 15 are 1, 3, 5, and 15. The factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors of 15 and 18 are 1 and 3.
Factors of 15: 1, 3, 5, and 15.Factors of 6: 1, 2, 3, and 6.Common factors (numbers on both lists): 1 and 3.Greatest common factor: 3 .
Factors of 6: 1, 2, 3, 6 Factors of 11: 1, 11 Factors of 15: 1, 3, 5, 15 GCF (6, 11, 15) = 1
The common factors of 120 and 150 are 1, 2, 3, 5, 6, 10, 15 and 30
Factors of 15 are 1, 3, 5, and 15. Factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. Common factors of 15 and 30 are 1, 3, 5, and 15.
One way to determine the common factors is to find all the factors of the numbers and compare them. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90. The common factors are 1, 2, 3, 5, 6, 10, 15, and 30. This also means the greatest common factor is 30.
