What's the Least Common Multiple (LCM) of 40 and 355?

Answer

LCM of 40 and 355 is 2,840

(Two thousand, eight hundred forty)

Finding LCM for 40 and 355 using GCF of these numbers

The first method to find LCM for numbers 40 and 355 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 355 is 5, so

LCM = (40 × 355) ÷ 5

LCM = 14200 ÷ 5

LCM = 2840

Finding LCM for 40 and 355 by Listing Multiples

The second method to find LCM for numbers 40 and 355 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

Multiples of 355: 355, 710, 1065, 1420, 1775, 2130, 2485, 2840, 3195, 3550

So the LCM for 40 and 355 is 2840

Finding LCM for 40 and 355 by Prime Factorization

Another method to find LCM for numbers 40 and 355 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 355: 5, 71 (exponent form: 51, 711)

23 × 51 × 711 = 2840
