What's the Least Common Multiple (LCM) of 40 and 630?

Answer: LCM of 40 and 630 is 2,520

(Two thousand, five hundred twenty)

Finding LCM for 40 and 630 using GCF's of these numbers

The first method to find LCM for numbers 40 and 630 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 630 is 10, so

LCM = (40 × 630) ÷ 10

LCM = 25200 ÷ 10

LCM = 2520

Finding LCM for 40 and 630 by Listing Multiples

The second method to find LCM for numbers 40 and 630 is to list out the common multiples for both nubmers and pick the first which matching:

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

Multiples of 630: 630, 1260, 1890, 2520, 3150, 3780

So the LCM for 40 and 630 is 2520

Finding LCM for 40 and 630 by Prime Factorization

Another method to find LCM for numbers 40 and 630 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 630: 2, 3, 3, 5, 7 (exponent form: 21, 32, 51, 71)

23 × 51 × 32 × 71 = 2520
