WebDec 8, 2024 · Step 1: Find the prime factorisation of both the numbers. Step 2: Find the common prime factors of the given numbers. Common factors = 2, 2, 2, 3 Step 3: Multiply all the common factors to find out the HCF. ∴ … WebMar 26, 2024 · So, the trick is we have to multiply the H.C.F of the two numbers with the non-common numbers from each of 30 and 42. The numbers which are not common in 30 and 42 are: 5 and 7 which you can see from the above prime factorization. 30 = 2 × 3 _ × 5. 42 = 2 × 3 _ × 7. In the above, the non-underlined numbers are the non-common numbers.
