What's the Least Common Multiple (LCM) of 90 and 135?

Answer

LCM of 90 and 135 is 270

(Two hundred seventy)

Finding LCM for 90 and 135 using GCF of these numbers

The first method to find LCM for numbers 90 and 135 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 90 and 135 is 45, so

LCM = (90 × 135) ÷ 45

LCM = 12150 ÷ 45

LCM = 270

Finding LCM for 90 and 135 by Listing Multiples

The second method to find LCM for numbers 90 and 135 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 90: 90, 180, 270, 360, 450

Multiples of 135: 135, 270, 405, 540

So the LCM for 90 and 135 is 270

Finding LCM for 90 and 135 by Prime Factorization

Another method to find LCM for numbers 90 and 135 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 90: 2, 3, 3, 5 (exponent form: 21, 32, 51)

All Prime Factors of 135: 3, 3, 3, 5 (exponent form: 33, 51)

21 × 33 × 51 = 270
