What's the Least Common Multiple (LCM) of 60 and 90?

Answer

LCM of 60 and 90 is
180

(One hundred eighty)

Finding LCM for 60 and 90 using GCF of these numbers

The first method to find LCM for numbers 60 and 90 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 60 and 90 is 30, so

LCM = (60 × 90) ÷ 30

LCM = 5,400 ÷ 30

LCM = 180

Finding LCM for 60 and 90 by Listing Multiples

The second method to find LCM for numbers 60 and 90 is to list out the common multiples for both numbers and pick the first one that matches:

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

Multiples of 90: 90, 180, 270, 360

So the LCM for 60 and 90 is 180

Finding LCM for 60 and 90 by Prime Factorization

Another method to find LCM for numbers 60 and 90 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 90: 2, 3, 3, 5 (exponent form: 21, 32, 51)

22 × 32 × 51 = 180
