What's the Least Common Multiple (LCM) of 40 and 195?

Answer

LCM of 40 and 195 is 1,560

(One thousand, five hundred sixty)

Finding LCM for 40 and 195 using GCF of these numbers

The first method to find LCM for numbers 40 and 195 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 195 is 5, so

LCM = (40 × 195) ÷ 5

LCM = 7800 ÷ 5

LCM = 1560

Finding LCM for 40 and 195 by Listing Multiples

The second method to find LCM for numbers 40 and 195 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, 1280, 1320, 1360, 1400, 1440, 1480, 1520, 1560, 1600, 1640

Multiples of 195: 195, 390, 585, 780, 975, 1170, 1365, 1560, 1755, 1950

So the LCM for 40 and 195 is 1560

Finding LCM for 40 and 195 by Prime Factorization

Another method to find LCM for numbers 40 and 195 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 195: 3, 5, 13 (exponent form: 31, 51, 131)

23 × 51 × 31 × 131 = 1560
