0The HCF is 7

The GCF is 21.

The GCF is 24.

The GCF is 7.

The GCF is 7.

If you mean: 21, 49 and 84 then the HCF is 7

GCF (21, 84, 91) = 7Factors of 21: 1, 3, 7, 21Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84Factors of 91: 1, 7, 13, 91GCF (21, 84, 91) = 7

The GCF is 21.

7 is the highest common factor of 21, 77 and 91.

The GCF is 7.

The Highest Common Factor is 7

49 = 7 x 7, 21 = 7 x 3, 91 = 7 x 13. HCF is 7

The GCF is 7.It is: 7

The GCF is 7.

HCF(21, 77, 84) = 7.

7 is the highest common factor of 21, 77 and 91.

Factors of 21: 1, 3, 7, 21Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84Factors of 91: 1, 7, 13, 91GCF (21, 84, 91) = 7

The GCF/HCF of 21 and 91 is 7. 21 = 3 x 7 91 = 7 x 13

HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2

The GCF of 21, 49, and 84 is 7.

First you express the numbers as the product of their prime factors: 28 = 2x2x7 21 = 3x7 Next you find the HCF. In this case, the HCF is 7. Finally, you multiply the numbers together and divide by the HCF. 28x21/7 = 84 Therefore the LCM of 28 and 21 is 84.

The GCF is 7.

84 : 104 = 21 : 26 (simplifying by dividing both sides of the ration by the hcf(84, 104) = 4)

The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84 The factors of 91 are: 1, 7, 13, 91

The GCF is 28.
