What is the greatest common factor of 10 21 and 42?
The GCF (greatest common factor) would be 21.
What is the greatest common factor of 13 and 27?
13 is a prime number & 27 = 3*3*3*1, so the greatest common factor of 13 and 27 would be 1, which is the only common factor.
Greatest common factor of 10 and 20?
20 - 1,2,4,5,10,20 You can not have a GCF of just one number. But written are the factors of 20.
What is the greatest common factor in 2 and 7?
The greatest common factor would be 14 because 7 times 2 = 14 and 2x7=14 The GCF= 14
What would be the greatest common factor of 16 and 28 and 48?
It is: 4
What is the greatest common factor of 16x2-8x?
I believe the GCF (Greatest Common Factor) would be 8x I believe the GCF (Greatest Common Factor) would be 8x
Factor out the greatest common monomial factor of this problem 4a-12?
I'm not clear on your terminology but I'm pretty sure it would look like this: 4(a-3). In this case 4 is the greatest common factor.
The greatest common factor of 17 and 52?
The greatest common factor of 17 and 52 would be 1.
What is the greatest common factor of 10 and 30-?
The greatest common factor is 10
What the greatest common factor of 20 40 80 and 140?

What are the greatest common factors of 155 and 867?
The greatest common factor would be 1.
Factor out the greatest common factor in 12xy2 plus 6x?
The greatest common factor of 12xy2 + 6x is 6x. The greatest common factor of 12 and 6 is 6, and the greatest common factor of xy2 and x is x. If you took 6x out of both factors, the end result would be 2y2+1
What is the greatest common factor of 10 25 and 5?
That would be 5, same as the least common factor.
What are the greatest common factor of 240?
The greatest common factor is a function of two numbers-- it is the greatest factor that the numbers have in common. The concept does not apply to a single number. Now you can use the same number twice and ask what is the greatest common factor of 240 and 240 and the answer would be 240.
What is the greatest common factor of 14b and 21ab?
The prime factors of 21 are 3 and 7.The prime factors of 14 are 2 and 7.The greatest common factor of 21 and 14 is 7.21ab and 14b also have another factor in common - b. So, the greatest common factor of 21ab and 14b would appear to be 7b . However, it is possible that a and 14 share a common factor of 2, in which case the greatest common factor of 21ab and 14b would be 14b.In summary, if a is an even number (i.e. having a factor of 2), the greatest common factor is 14b.If a is not an even number, the greatest common factor is 7b.gcf(21ab, 14b) = 7b.
What is the greatest common factor of 13 and 63?
The greatest common factor would be 1. Since 63 is not divisable by 13.
