The factors of the numbers are
12: 1, 2, 3, 4, 6, and 12
15: 1, 3, 5, and 15
30: 1, 2, 3, 5, 6, 10, 15, and 30
The GCF of the three numbers is the largest number that is a factor of all three numbers, which is 3.
The greatest common factor of the numbers 15 and 12 is 3.
The GCF of 12 and 15 is 3. factors of 12: 1, 2, 3, 4, 6 and 12. factors of 15: 1, 3, 5, and 15. common factors 1 and 3. Since 3 > 1, 3 is the Greatest Common Factor.
There is no "greatest common multiple" for any pair of numbers. If you meant greatest common factor, the answer is 3.
The GCF is... 1! 1 is the only factor common to all three numbers.
