What's the Least Common Multiple (LCM) of 40 and 395?

Answer

LCM of 40 and 395 is 3,160

(Three thousand, one hundred sixty)

Finding LCM for 40 and 395 using GCF of these numbers

The first method to find LCM for numbers 40 and 395 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 395 is 5, so

LCM = (40 × 395) ÷ 5

LCM = 15800 ÷ 5

LCM = 3160

Finding LCM for 40 and 395 by Listing Multiples

The second method to find LCM for numbers 40 and 395 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, 1680, 1720, 1760, 1800, 1840, 1880, 1920, 1960, 2000, 2040, 2080, 2120, 2160, 2200, 2240, 2280, 2320, 2360, 2400, 2440, 2480, 2520, 2560, 2600, 2640, 2680, 2720, 2760, 2800, 2840, 2880, 2920, 2960, 3000, 3040, 3080, 3120, 3160, 3200, 3240

Multiples of 395: 395, 790, 1185, 1580, 1975, 2370, 2765, 3160, 3555, 3950

So the LCM for 40 and 395 is 3160

Finding LCM for 40 and 395 by Prime Factorization

Another method to find LCM for numbers 40 and 395 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 395: 5, 79 (exponent form: 51, 791)

23 × 51 × 791 = 3160
