The GCF is 7.

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

The hcf is 21

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.

hcf = 42, lcm = 84.
