HCF of 20 and 21 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly. 1. Step 1: Divide21 (larger number) by 20 (smaller number). 2. Step 2:Since the remainder ≠ 0, we will divide the divisor of step 1 (20) by the remainder (1). 3. Step 3:Repeat this process until the … See more Prime factorization of 20 and 21 is (2 × 2 × 5) and (3 × 7) respectively.
