WebSolution: Step 1: To find HCF of 20 and 12, write each number as a product of prime factors. 20 = 2 × 2 × 5 = 2 2 × 5. 12 = 2 × 2 × 3 = 2 2 × 3. Step 2: Multiply all the common prime factors with the lowest degree. Here we have only 2 as a common prime factor with the lowest power of 2. HCF of 20 and 12 = 2 2 = 4. WebStep - 1: Find the required answer using definition of co-prime numbers. By definition of co-prime numbers, Two numbers having only 1 as their common factor are called co-prime numbers. So, HCF of two co-prime numbers is 1. Hence, the correct option is A.
