What's the Least Common Multiple (LCM) of 60 and 72?

Answer: LCM of 60 and 72 is 360

(Three hundred sixty)

Finding LCM for 60 and 72 using GCF's of these numbers

The first method to find LCM for numbers 60 and 72 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 60 and 72 is 12, so

LCM = (60 × 72) ÷ 12

LCM = 4320 ÷ 12

LCM = 360

Finding LCM for 60 and 72 by Listing Multiples

The second method to find LCM for numbers 60 and 72 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 60: 60, 120, 180, 240, 300, 360, 420, 480

Multiples of 72: 72, 144, 216, 288, 360, 432, 504

So the LCM for 60 and 72 is 360

Finding LCM for 60 and 72 by Prime Factorization

Another method to find LCM for numbers 60 and 72 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 60: 2, 2, 3, 5 (exponent form: 2², 3¹, 5¹)

All Prime Factors of 72: 2, 2, 2, 3, 3 (exponent form: 2³, 3²)

2³ × 3² × 5¹ = 360
