7 is the highest common factor of 21, 77 and 91.
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
The GCF is 7.
The GCF is 7.
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.
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
The GCF is 7.
Well, isn't that a happy little math question! To find the highest common factor (HCF) of 28, 84, and 91, we can start by listing the factors of each number. The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The factors of 91 are 1, 7, 13, and 91. The largest number that appears in all three lists is 7, so the HCF of 28, 84, and 91 is 7.
