hcf = 42, lcm = 84.
The GCF is 28.
The GCF is 7.
The GCF is 24.
7
The Highest Common Factor (HCF) of 21, 77, and 84 is 7. To find the HCF, you need to identify the common factors of the numbers and determine the highest one they all share. In this case, the factors of 21 are 1, 3, 7, 21; the factors of 77 are 1, 7, 11, 77; and the factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84. The highest common factor among them is 7.
The GCF is 2.
The GCF is 7.
If you mean: 21, 49 and 84 then the HCF is 7
If you mean 28, 49 and 84 then the hcf is 7
The HCF of the given numbers is 14
