What's the Least Common Multiple (LCM) of 20 and 415?

Answer

LCM of 20 and 415 is 1,660

(One thousand, six hundred sixty)

Finding LCM for 20 and 415 using GCF of these numbers

The first method to find LCM for numbers 20 and 415 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 20 and 415 is 5, so

LCM = (20 × 415) ÷ 5

LCM = 8300 ÷ 5

LCM = 1660

Finding LCM for 20 and 415 by Listing Multiples

The second method to find LCM for numbers 20 and 415 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400, 420, 440, 460, 480, 500, 520, 540, 560, 580, 600, 620, 640, 660, 680, 700, 720, 740, 760, 780, 800, 820, 840, 860, 880, 900, 920, 940, 960, 980, 1000, 1020, 1040, 1060, 1080, 1100, 1120, 1140, 1160, 1180, 1200, 1220, 1240, 1260, 1280, 1300, 1320, 1340, 1360, 1380, 1400, 1420, 1440, 1460, 1480, 1500, 1520, 1540, 1560, 1580, 1600, 1620, 1640, 1660, 1680, 1700

Multiples of 415: 415, 830, 1245, 1660, 2075, 2490

So the LCM for 20 and 415 is 1660

Finding LCM for 20 and 415 by Prime Factorization

Another method to find LCM for numbers 20 and 415 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 20: 2, 2, 5 (exponent form: 22, 51)

All Prime Factors of 415: 5, 83 (exponent form: 51, 831)

22 × 51 × 831 = 1660
