hcf = 42, lcm = 84.

The GCF is 7.

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

Whenever one of the numbers is a multiple of the other, the larger number is the LCM and the smaller number is the GCF. In this case, the difference between them is 42. The highest common multiple of any set of integers is infinite.

The GCF is 42.

The Highest Common Factor (HCF) of 42, 49, and 84 is 7. To find the HCF, you need to factorize each number into its prime factors. The prime factors of 42 are 2 x 3 x 7, the prime factors of 49 are 7 x 7, and the prime factors of 84 are 2 x 2 x 3 x 7. The HCF is the product of the common prime factors raised to the lowest power they appear in any of the numbers, which in this case is 7.
