factors are whole numbers except 1 by which a large number can be divided

Prime factors are factors of a number that are themselves prime numbers

HCF is found by finding all common factors of two numbers and selecting the largest one.

Think about the relationship between H.C.F and L.C.M.

use formula lcm x hcf = a x b where a and b are product of two numbers
