gcf(39, 91) = 13
3, 13, and 17 share no common factors aside from 1. Hence, the gcf of 3, 13, and 17 is 1.
Prime factorization of: 195= 3 x 5 x 13 273= 3 x .....13 x 7 =============== GCF=3 x .....13 GCF=39
The GCF is 3.
3 x 13 and 3 x 11 so GCF = 3
The GCF is 13. 39=13*3 169=13*13
Since 65 is a factor of 520, it is automatically the GCF.
The prime factors are: 39 = 3 * 13 143 = 11 * 13 156 = 2 * 2 * 3 * 13 So the greatest common factor is 13.
The greatest common factor of 51, 66, and 39 is 3. Work shown below 51 = 3 * 17 66 = 2 * 3 * 11 39 = 3 * 13
The GCF of 91 and 156 is 13.The prime factorization of 91 is 7*13.The prime factorization of 156 is 2*2*3*13So the GCF is 13.
The GCF is 13.
13 is the highest common factor of 78, 91 and 156.
