What's the Least Common Multiple (LCM) of 40 and 415?

Answer

LCM of 40 and 415 is 3,320

(Three thousand, three hundred twenty)

Finding LCM for 40 and 415 using GCF of these numbers

The first method to find LCM for numbers 40 and 415 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 415 is 5, so

LCM = (40 × 415) ÷ 5

LCM = 16600 ÷ 5

LCM = 3320

Finding LCM for 40 and 415 by Listing Multiples

The second method to find LCM for numbers 40 and 415 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, 3280, 3320, 3360, 3400

Multiples of 415: 415, 830, 1245, 1660, 2075, 2490, 2905, 3320, 3735, 4150

So the LCM for 40 and 415 is 3320

Finding LCM for 40 and 415 by Prime Factorization

Another method to find LCM for numbers 40 and 415 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 415: 5, 83 (exponent form: 51, 831)

23 × 51 × 831 = 3320
