The GCF of 7440 and 13020 is 1860
91 has the factors 7 and 13 143 has the factors 11 and 13 thus the GCF is 13
26 = 2 x 1391 = 7 x 13So the GCF of 26 and 91 is 13.The GCF is 13.
The GCF of 91 and 130 is 13.91 = 7 * 13.130 = 10 * 13.Hence their GCF is 13.
Factor them. 7 x 7 = 49 7 x 13 = 91 Select the common factor. The GCF is 7.
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.
91 and 1 respectively
1 and 91, respectively.
The GCF is 7. (7 x 9) + (7 x 7) + (7 x 13) = 7 x 29
