Step 1

To factor 60 into its prime factors, we divide it by the smallest prime number that can divide it evenly and continue the process with the quotient until we reach 1. 60 ÷ 2 = 30 30 ÷ 2 = 15 15 ÷ 3 = 5 5 ÷ 5 = 1 Now, we can write 60 as a product of its prime Show more…

Find the HCF and LCM of 60 and 80 by following the steps below: 1. Write 60 as a product of its prime factors. 2. Write 80 as a product of its prime factors. 3. Multiply the factors that appear in both lists from steps 1 and 2. This gives you the HCF of 60 and 80. 4. Multiply all the possible factors of both numbers listed in step 1. This gives you the LCM of 60 and 80.
