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 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.
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
To find the Highest Common Factor (HCF) of 35, 77, and 91, you need to factorize each number. The factors of 35 are 1, 5, 7, 35. The factors of 77 are 1, 7, 11, 77. The factors of 91 are 1, 7, 13, 91. The common factor among these three numbers is 7, so the HCF of 35, 77, and 91 is 7.
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
