What's the Least Common Multiple (LCM) of 45 and 50?

Answer

LCM of 45 and 50 is 450

(Four hundred fifty)

Finding LCM for 45 and 50 using GCF of these numbers

The first method to find LCM for numbers 45 and 50 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 45 and 50 is 5, so

LCM = (45 × 50) ÷ 5

LCM = 2250 ÷ 5

LCM = 450

Finding LCM for 45 and 50 by Listing Multiples

The second method to find LCM for numbers 45 and 50 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 45: 45, 90, 135, 180, 225, 270, 315, 360, 405, 450, 495, 540

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

So the LCM for 45 and 50 is 450

Finding LCM for 45 and 50 by Prime Factorization

Another method to find LCM for numbers 45 and 50 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 45: 3, 3, 5 (exponent form: 32, 51)

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

32 × 52 × 21 = 450
