What's the Least Common Multiple (LCM) of 20 and 160?

Answer

LCM of 20 and 160 is 160

(One hundred sixty)

Finding LCM for 20 and 160 using GCF of these numbers

The first method to find LCM for numbers 20 and 160 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 20 and 160 is 20, so

LCM = (20 × 160) ÷ 20

LCM = 3200 ÷ 20

LCM = 160

Finding LCM for 20 and 160 by Listing Multiples

The second method to find LCM for numbers 20 and 160 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

Multiples of 160: 160, 320, 480

So the LCM for 20 and 160 is 160

Finding LCM for 20 and 160 by Prime Factorization

Another method to find LCM for numbers 20 and 160 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 160: 2, 2, 2, 2, 2, 5 (exponent form: 25, 51)

25 × 51 = 160
