What's the Least Common Multiple (LCM) of 20 and 150?

Answer

LCM of 20 and 150 is 300

(Three hundred)

Finding LCM for 20 and 150 using GCF of these numbers

The first method to find LCM for numbers 20 and 150 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 20 and 150 is 10, so

LCM = (20 × 150) ÷ 10

LCM = 3000 ÷ 10

LCM = 300

Finding LCM for 20 and 150 by Listing Multiples

The second method to find LCM for numbers 20 and 150 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340

Multiples of 150: 150, 300, 450, 600

So the LCM for 20 and 150 is 300

Finding LCM for 20 and 150 by Prime Factorization

Another method to find LCM for numbers 20 and 150 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 20: 2, 2, 5 (exponent form: 22, 51)

All Prime Factors of 150: 2, 3, 5, 5 (exponent form: 21, 31, 52)

22 × 52 × 31 = 300
