The factors of 28 are:
1, 2, 4, 7, 14, 28
The factors of 77 are:
1, 7, 11, 77
The factors of 91 are:
1, 7, 13, 91
The GCF is 7.
The HCF of 28 77 and 91 is 7, since 7 goes into all the numbers and all the numbers above it dont.
The GCF is 7.
28 = 4 x 777 = 11 x 7 91 = 13 x 7 Great common factor = 4 x 11 x 13 x 7 = 44 x 91 = 4004
1 and 7
The GCF is 7.
The factors of 1001 are: 1 7 11 13 77 91 143 1001
7 is the Greatest Common Factor (GCF) Factored into their prime factors: 28 = 2 x 2 x 7 77 = 7 x 11 91 = 7 x 13 The only factor they have in common (other than 1) is 7
1,2,4,7,14,28 1,7,11,77
The factors of 1001 are 1, 7, 11, 13, 77, 91, 143, 1001. For them to be common, they need to be compared to another set of factors.

(-33/91) / (-3/77) =(33/91) / (3/77) = (33/91) * (77/3) = (11/91)*(77/1) =(11/13)*(11/1) = 121/13(-33/91) / (-3/77) =(33/91) / (3/77) = (33/91) * (77/3) = (11/91)*(77/1) =(11/13)*(11/1) = 121/13(-33/91) / (-3/77) =(33/91) / (3/77) = (33/91) * (77/3) = (11/91)*(77/1) =(11/13)*(11/1) = 121/13(-33/91) / (-3/77) =(33/91) / (3/77) = (33/91) * (77/3) = (11/91)*(77/1) =(11/13)*(11/1) = 121/13
