What's the Least Common Multiple (LCM) of 20 and 190?

Answer

LCM of 20 and 190 is 380

(Three hundred eighty)

Finding LCM for 20 and 190 using GCF of these numbers

The first method to find LCM for numbers 20 and 190 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 20 and 190 is 10, so

LCM = (20 × 190) ÷ 10

LCM = 3800 ÷ 10

LCM = 380

Finding LCM for 20 and 190 by Listing Multiples

The second method to find LCM for numbers 20 and 190 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, 360, 380, 400, 420

Multiples of 190: 190, 380, 570, 760

So the LCM for 20 and 190 is 380

Finding LCM for 20 and 190 by Prime Factorization

Another method to find LCM for numbers 20 and 190 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 190: 2, 5, 19 (exponent form: 21, 51, 191)

22 × 51 × 191 = 380
