What's the Least Common Multiple (LCM) of 20 and 440?

Answer

LCM of 20 and 440 is 440

(Four hundred forty)

Finding LCM for 20 and 440 using GCF of these numbers

The first method to find LCM for numbers 20 and 440 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 20 and 440 is 20, so

LCM = (20 × 440) ÷ 20

LCM = 8800 ÷ 20

LCM = 440

Finding LCM for 20 and 440 by Listing Multiples

The second method to find LCM for numbers 20 and 440 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, 440, 460, 480

Multiples of 440: 440, 880, 1320

So the LCM for 20 and 440 is 440

Finding LCM for 20 and 440 by Prime Factorization

Another method to find LCM for numbers 20 and 440 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 440: 2, 2, 2, 5, 11 (exponent form: 23, 51, 111)

23 × 51 × 111 = 440
