WebExample 1: Two simple composite numbers. Calculate the highest common factor of 18 and 24. State the product of prime factors for each number, not in index form. 18 = 2 × 3 × 3. 24 = 2 × 2 × 2 × 3. 2 Write all the prime factors into the Venn diagram for each number. 3 Multiply the prime factors in the intersection to find the HCF. WebIn 18, there is 32 and in 24, there is 3. Between 32 and 3, select 3, as it is the factor common to 18 and 24 with the least power. Now HCF is product of 2 and 3, i.e. 2 × 3 = 6
