What's the Least Common Multiple (LCM) of 9 and 8?

Answer

LCM of 9 and 8 is 72

(Seventy-two)

Finding LCM for 9 and 8 using GCF of these numbers

The first method to find LCM for numbers 9 and 8 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 9 and 8 is 1, so

LCM = (9 × 8) ÷ 1

LCM = 72 ÷ 1

LCM = 72

Finding LCM for 9 and 8 by Listing Multiples

The second method to find LCM for numbers 9 and 8 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90

Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88

So the LCM for 9 and 8 is 72

Finding LCM for 9 and 8 by Prime Factorization

Another method to find LCM for numbers 9 and 8 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 9: 3, 3 (exponent form: 32)

All Prime Factors of 8: 2, 2, 2 (exponent form: 23)

32 × 23 = 72
