What's the Least Common Multiple (LCM) of 30 and 180?

Answer

LCM of 30 and 180 is 180

(One hundred eighty)

Finding LCM for 30 and 180 using GCF of these numbers

The first method to find LCM for numbers 30 and 180 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 30 and 180 is 30, so

LCM = (30 × 180) ÷ 30

LCM = 5400 ÷ 30

LCM = 180

Finding LCM for 30 and 180 by Listing Multiples

The second method to find LCM for numbers 30 and 180 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 30: 30, 60, 90, 120, 150, 180, 210, 240

Multiples of 180: 180, 360, 540

So the LCM for 30 and 180 is 180

Finding LCM for 30 and 180 by Prime Factorization

Another method to find LCM for numbers 30 and 180 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

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

All Prime Factors of 180: 2, 2, 3, 3, 5 (exponent form: 22, 32, 51)

22 × 32 × 51 = 180
