What's the Least Common Multiple (LCM) of 50 and 90?

Answer

LCM of 50 and 90 is
450

(Four hundred fifty)

Finding LCM for 50 and 90 using GCF of these numbers

The first method to find LCM for numbers 50 and 90 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 50 and 90 is 10, so

LCM = (50 × 90) ÷ 10

LCM = 4,500 ÷ 10

LCM = 450

Finding LCM for 50 and 90 by Listing Multiples

The second method to find LCM for numbers 50 and 90 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 50: 50, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550

Multiples of 90: 90, 180, 270, 360, 450, 540, 630

So the LCM for 50 and 90 is 450

Finding LCM for 50 and 90 by Prime Factorization

Another method to find LCM for numbers 50 and 90 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 50: 2, 5, 5 (exponent form: 21, 52)

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

21 × 52 × 32 = 450
