51 = 1 x 3 x 17; 221 = 1 x 13 x 17. GCF is 1 x 17 = 17.
Since 65 is a factor of 520, it is automatically the GCF.
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 51 and 65 is 1. The prime factorization of 51 is 3*17. The prime factorization of 65 is 5*13 They have no factors in common other than 1.
gcf(39, 91) = 13
The GCF is 1.
