To find the Highest Common Factor (HCF) of 42, 77, and 84, you first need to find the prime factors of each number. The prime factors of 42 are 2, 3, and 7. The prime factors of 77 are 7 and 11. The prime factors of 84 are 2, 3, and 7. To find the HCF, you need to identify the common prime factors and multiply them together. In this case, the HCF of 42, 77, and 84 is 7.
7
HCF is the highest common factor of two or more numbers. HCF of 56 and 49 is 7.
49 = 7 x 7, 21 = 7 x 3, 91 = 7 x 13. HCF is 7
HCF = 56 LCM = 8008 616 = 2^3 x 7 x 11 728 = 2^3 x 7 x 13 hcf = 2^3 x 7 = 56 lcm = 2^3 x 7 x 11 x 13 = 8008
The HCF is 7.
The GCF is 42.
The GCF is 7.
Factors of 18 are 3,3,& 2. Factors of 21 are 3 & 7 One lot of '3' is common to both so '3' is the HCF.
