three
9/3 = 3 = 15/5
What is the greatest common factor of 9, 18, and 15.The answer is....3
-- The common factors of 3, 15, and 9 are 1 and 3 . -- Their greatest common factor is 3 . -- When discussing numbers, there is no such thing as the 'most' common factor.
HCF of 9 and 15 is 3
factors: 9: 1,3,9 15: 1,3,5,15 common afctors: 1,3 greatest common factor: 3
No, but it is a common multiple.
3
3
The factors of 9 are 1, 3, and 9. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 15 are 1, 3, 5, and 15. The common factors of 9, 12, and 15 are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1.
One is the only common factor of 8 9 13 and 15?
The greatest common factor of 3, 15 and 9 is 3
The least common factor of any set of numbers is 1.
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.
