What's the Least Common Multiple (LCM) of 36 and 90?

Answer: LCM of 36 and 90 is 180

(One hundred eighty)

Finding LCM for 36 and 90 using GCF's of these numbers

The first method to find LCM for numbers 36 and 90 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 36 and 90 is 18, so

LCM = (36 × 90) ÷ 18

LCM = 3240 ÷ 18

LCM = 180

Finding LCM for 36 and 90 by Listing Multiples

The second method to find LCM for numbers 36 and 90 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 36: 36, 72, 108, 144, 180, 216, 252

Multiples of 90: 90, 180, 270, 360

So the LCM for 36 and 90 is 180

Finding LCM for 36 and 90 by Prime Factorization

Another method to find LCM for numbers 36 and 90 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 36: 2, 2, 3, 3 (exponent form: 2², 3²)

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

2² × 3² × 5¹ = 180
