91 has the factors 7 and 13 143 has the factors 11 and 13 thus the GCF is 13
its 13 but to get it u can do factor trees that's how i do it
The GCF of 13 and 52 is 13.
The GCF is 7.
The GCF is: 13
The GCF of 169 and 343 is 1.
The GCF is 13.
The GCF is 1.
91 has the factors 7 and 13 143 has the factors 11 and 13 thus the GCF is 13
The GCF of 7440 and 13020 is 1860
104 / 91 =1 r 13 91 / 13 = 7 r 0 gcf of 104 and 91 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 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.
Factor them. 7 x 7 = 49 7 x 13 = 91 Select the common factor. The GCF is 7.
Prime factorization of: 195= 3 x 5 x 13 273= 3 x .....13 x 7 =============== GCF=3 x .....13 GCF=39
1 and 91, respectively.
91 and 1 respectively
