2, 3, 5, 7, and 11 are all prime numbers.
Each has only two factors ... itself and '1'.
The greatest factor common among them is the only factor common among them ... '1'.
275 factor=5*5*11 396=2*2*3*3*11 11 is the GCF
The GCF is 2^3 x 5.
The GCF is 1.
15=1*3*5 40=1*2*2*2*5 gcf=5
2 x 3 = 6 2 x 5 = 10 The GCF is 2.
275 factor=5*5*11 396=2*2*3*3*11 11 is the GCF
The factors of 55 are 5 and 11 The factors of 132 are 2, 2, 3, and 11 The factors of 143 are 13 and 11 The GCF is thus 11
The GCF is 2^3 x 5.
Prime factorization of: 30 = 2 x 3 x 5 44 = 2 x..........2 x 11 ================ GCF=2
110=2*5*11 240=2*2*2*2*3*5. GCF=2
45,375 = 3 x 5^5^3 x 11^2175,175 = 5^2 x 7 x 11 x 91Then the GCF is 275 (5^2 x 11).
The GCF is 1.
gcf(2, 5, 11) = 1.
The greatest common factor of 55 (5 x 11) and 105 (3 x 5 x 7) is 5.
The GCF is 1.
factoring 120=2*2*2*3*5 88=2*2*2*11 common ones=2*2*2=8
The systematic way to get the answer is: 90 = 2*3*3*5 210 = 2*3*5*7 So gcf is 2*3*5 = 30
