Question

Find HCF of 18 and 30 by prime factorization method.

Answer 1

Final answer: HCF of 18 and 30 by prime factorization method is 6.

Given that: We are given 18 and 30

To find: We have to find HCF of 18 and 30 by prime factorization method.

Explanation:

• There are three steps to find HCF of two numbers by prime factorization method.

Step 1: Calculate the prime factorization of the given numbers.

Step 2: Find common prime factors between the given numbers.

Step 3: The product of common prime factors with lowest exponential power is the H.C.F of the given numbers.

• Here we have to find HCF of 18 and 30.

Step 1: prime factorization of 18 = 2*3*3

           prime factorization of 30 = 2*3*5

Step 2: 2 *3 is common for both 18 and 30

Step 3: HCF of 18 and 30 is 2*3=6

• Hence, HCF of 18 and 30 by prime factorization method is 6.
