Since 2 is a factor of 12, it is automatically the GCF.
The GCF is 2.
A greatest common factor is the largest factor between two or more numbers. For example, the greatest common factor of 10 and 12 is 2. Because the factors of 10 are 1,2,5, and 10 and the factors of 12 are 1,2,3,4,6, and 12. Since 2 is the largest factor that they both share, it is the greatest common factor.
To get the greatest (not greater) common factor GCF, factor each number into primes: 60 = 2*2*3*5 72 = 2*2*2*3*3 Which prime factors are common to both numbers? Two 2's and one 3. GCF = 2*2*3 = 12
The greatest common factor of two and four is 2.
The Greatest Common Factor of 12 and 10 is 2.
Since 12 is a factor of 72, all of its factors are common.
You need at least two numbers to find a GCF.
The GCF is 2.
The greatest common factor of 12 and 14 is 2.
The greatest common factor of 8, 10, and 12 is 2.
2
The greatest common factor of 12 and 34 is 2.
