The GCF is 1.
What is the greatest common factor shared by 51 and 21?
Since 70 is a factor of 490, it is automatically the GCF.
Since 70 is a factor of 700, it is automatically the GCF.
10 = 2 * 5 15 = 3 * 5 The shared prime factor is 5. Another way to find this is by finding the greatest common denominator (gcd).
The greatest common factor (GCF) is: 5The GCF is 5.
It is 10
It is: 10
It is 10
Since 5 is a factor of 15, it is automatically the GCF.
Factors of 70: 1, 2, 5, 7, 10, 14, 35, 70Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30GCF (70, 30) = 10
The GCF is 5.
