Solution

Step 1: Explain how to find LCM of two numbers

The Least Common factor can be calculated in two ways; with the LCM formula calculation of Highest Common Factor (H.C.F), or multiplying the prime factors with the highest exponent factor.

Step 2: Find the LCM

Prime factors of 7 is

7=1×7

Prime factors of 9 is

9=3×3

HCF(7,9)=1LCM(7,9)=7×91=631=63

Hence, the LCM of 7 and 9 is 63.
