7 (7 x 19, 7 x 31)
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
35. 350 = 2 x 52 x 7 385 = 5 x 7 x 11 hcf = 5 x 7 = 35
The Highest Common Factor is 11
The first two are prime so their hcf, and that of all three numbers, is 1.
what is the HCF for 11 33 121
Divide numerator and denominator by their HCF eg 35/77: HCF is 7 so simplifies to 5/11.
