LCM for 140 and 160

What's the Least Common Multiple (LCM) of 140 and 160?

Answer: LCM of 140 and 160 is 1,120

(One thousand, one hundred twenty)

Finding LCM for 140 and 160 using GCF's of these numbers

The first method to find LCM for numbers 140 and 160 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 140 and 160 is 20, so

LCM = (140 × 160) ÷ 20

LCM = 22400 ÷ 20

LCM = 1120

Finding LCM for 140 and 160 by Listing Multiples

The second method to find LCM for numbers 140 and 160 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 140: 140, 280, 420, 560, 700, 840, 980, 1120, 1260, 1400

Multiples of 160: 160, 320, 480, 640, 800, 960, 1120, 1280, 1440

So the LCM for 140 and 160 is 1120

Finding LCM for 140 and 160 by Prime Factorization

Another method to find LCM for numbers 140 and 160 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 140: 2, 2, 5, 7 (exponent form: 22, 51, 71)

All Prime Factors of 160: 2, 2, 2, 2, 2, 5 (exponent form: 25, 51)

25 × 51 × 71 = 1120
