What's the Least Common Multiple (LCM) of 6 and 30?

Answer: LCM of 6 and 30 is 30

(Thirty)

Finding LCM for 6 and 30 using GCF's of these numbers

The first method to find LCM for numbers 6 and 30 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 6 and 30 is 6, so

LCM = (6 × 30) ÷ 6

LCM = 180 ÷ 6

LCM = 30

Finding LCM for 6 and 30 by Listing Multiples

The second method to find LCM for numbers 6 and 30 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 6: 6, 12, 18, 24, 30, 36, 42

Multiples of 30: 30, 60, 90, 120, 150, 180, 210, [...], 30

So the LCM for 6 and 30 is 30

Finding LCM for 6 and 30 by Prime Factorization

Another method to find LCM for numbers 6 and 30 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 6: 2, 3 (exponent form: 2¹, 3¹)

All Prime Factors of 30: 2, 3, 5 (exponent form: 2¹, 3¹, 5¹)

2¹ × 3¹ × 5¹ = 30
