What's the Least Common Multiple (LCM) of 40 and 315?

Answer

LCM of 40 and 315 is 2,520

(Two thousand, five hundred twenty)

Finding LCM for 40 and 315 using GCF of these numbers

The first method to find LCM for numbers 40 and 315 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 315 is 5, so

LCM = (40 × 315) ÷ 5

LCM = 12600 ÷ 5

LCM = 2520

Finding LCM for 40 and 315 by Listing Multiples

The second method to find LCM for numbers 40 and 315 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

Multiples of 315: 315, 630, 945, 1260, 1575, 1890, 2205, 2520, 2835, 3150

So the LCM for 40 and 315 is 2520

Finding LCM for 40 and 315 by Prime Factorization

Another method to find LCM for numbers 40 and 315 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 315: 3, 3, 5, 7 (exponent form: 32, 51, 71)

23 × 51 × 32 × 71 = 2520
