The GCF is 1.
80= 2*2*2*2*5 35= 5*7 The only factor they have in common is 5, so the answer is 5.
The greatest common factor -- in fact, the only common factor -- of 2, 5, and 8 is the number 1.
The Greatest Common Factor of 5, 315, 2: 1
The greatest common factor of 2, 5, and 6 is 1
The only common factor of 15, 2 and 5 is 1.
The GCF is 2.
12 = 2 * 2 * 3 50 = 2 * * 5 * 5 ---------------------------- The only common factor is 2. ---------------------------- GCF = 2
The greatest common factor of 2, 4, and 5 is 1.
10 = 2 x 5 25 = 5 x 5 The only factor the two numbers have in common is 5. Then that must be the greatest common factor.
The greatest common factor of 20 and 555 is 5. The prime factorization of 20 is 2*2*5 The prime factorization of 555 is 3*5*37 So the greatest common factor is 5.
This question cannot be answered as all three numbers do not share a common factor. 2 has 2 as its only factor 5 has 5 as its only factor 10 has 2 and 5 as its factors. As you can see the three numbers do not contain a common factor, but 10 does have both the other numbers as factors.
The greatest common factor of 2 and 5 is 1
