What's the Least Common Multiple (LCM) of 4 and 9?

Answer

LCM of 4 and 9 is 36

(Thirty-six)

Finding LCM for 4 and 9 using GCF of these numbers

The first method to find LCM for numbers 4 and 9 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 4 and 9 is 1, so

LCM = (4 × 9) ÷ 1

LCM = 36 ÷ 1

LCM = 36

Finding LCM for 4 and 9 by Listing Multiples

The second method to find LCM for numbers 4 and 9 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44

Multiples of 9: 9, 18, 27, 36, 45, 54

So the LCM for 4 and 9 is 36

Finding LCM for 4 and 9 by Prime Factorization

Another method to find LCM for numbers 4 and 9 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 4: 2, 2 (exponent form: 22)

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

22 × 32 = 36
