We found the factors and prime factorization of 12 and 15. The biggest common factor number is the GCF number. So the greatest common factor 12 and 15 is 3..
In this manner, what is the GCF of 12?
Finding the Greatest Common Factor
| Two Numbers | Factors | Common Factors |
| 9 and 12 | 9: 1,3,9 12: 1,2,3,4,6,12 | 1,3 |
Secondly, what is the greatest common factor of 12 and 20? Greatest common factor (GCF) of 12 and 20 is 4. We will now calculate the prime factors of 12 and 20, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 12 and 20.
Accordingly, how can you find the factors of 12 and 15?
HCF Example The factors of 12 are : 1, 2, 3, 4, 6, 12. The factors of 15 are : 1, 3, 5, 15. 1 and 3 are the only common factors (numbers which are factors of both 12 and 15). Therefore, the highest common factor of 12 and 15 is 3.
What is the GCF of 12 and 18?
Greatest common factor (GCF) of 12 and 18 is 6.
