What's the Least Common Multiple (LCM) of 18 and 60?

Answer: LCM of 18 and 60 is 180

(One hundred eighty)

Finding LCM for 18 and 60 using GCF's of these numbers

The first method to find LCM for numbers 18 and 60 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 18 and 60 is 6, so

LCM = (18 × 60) ÷ 6

LCM = 1080 ÷ 6

LCM = 180

Finding LCM for 18 and 60 by Listing Multiples

The second method to find LCM for numbers 18 and 60 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216

Multiples of 60: 60, 120, 180, 240, 300

So the LCM for 18 and 60 is 180

Finding LCM for 18 and 60 by Prime Factorization

Another method to find LCM for numbers 18 and 60 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 18: 2, 3, 3 (exponent form: 2¹, 3²)

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

2² × 3² × 5¹ = 180
