Question

Three numbers are given below. Use prime factorisation to determine the HCF and LCM 1848, 132 and 462​

Answer 1

The HCF is the highest common factor of 1848, 132 and 462, which is 14.

Explanation:

Prime factorisation is a mathematical method that breaks a number down into its prime factors, the smallest positive integers that are multiples of that number.

The highest common factor of 1848, 132 and 462 is the smallest number that divides all three.

The lowest common multiple is the smallest number that multiples all three numbers!
