What's the Least Common Multiple (LCM) of 40 and 290?

Answer

LCM of 40 and 290 is 1,160

(One thousand, one hundred sixty)

Finding LCM for 40 and 290 using GCF of these numbers

The first method to find LCM for numbers 40 and 290 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 290 is 10, so

LCM = (40 × 290) ÷ 10

LCM = 11600 ÷ 10

LCM = 1160

Finding LCM for 40 and 290 by Listing Multiples

The second method to find LCM for numbers 40 and 290 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440, 480, 520, 560, 600, 640, 680, 720, 760, 800, 840, 880, 920, 960, 1000, 1040, 1080, 1120, 1160, 1200, 1240

Multiples of 290: 290, 580, 870, 1160, 1450, 1740

So the LCM for 40 and 290 is 1160

Finding LCM for 40 and 290 by Prime Factorization

Another method to find LCM for numbers 40 and 290 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 40: 2, 2, 2, 5 (exponent form: 23, 51)

All Prime Factors of 290: 2, 5, 29 (exponent form: 21, 51, 291)

23 × 51 × 291 = 1160
