What's the Least Common Multiple (LCM) of 30 and 445?

Answer

LCM of 30 and 445 is 2,670

(Two thousand, six hundred seventy)

Finding LCM for 30 and 445 using GCF of these numbers

The first method to find LCM for numbers 30 and 445 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 30 and 445 is 5, so

LCM = (30 × 445) ÷ 5

LCM = 13350 ÷ 5

LCM = 2670

Finding LCM for 30 and 445 by Listing Multiples

The second method to find LCM for numbers 30 and 445 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 30: 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, 420, 450, 480, 510, 540, 570, 600, 630, 660, 690, 720, 750, 780, 810, 840, 870, 900, 930, 960, 990, 1020, 1050, 1080, 1110, 1140, 1170, 1200, 1230, 1260, 1290, 1320, 1350, 1380, 1410, 1440, 1470, 1500, 1530, 1560, 1590, 1620, 1650, 1680, 1710, 1740, 1770, 1800, 1830, 1860, 1890, 1920, 1950, 1980, 2010, 2040, 2070, 2100, 2130, 2160, 2190, 2220, 2250, 2280, 2310, 2340, 2370, 2400, 2430, 2460, 2490, 2520, 2550, 2580, 2610, 2640, 2670, 2700, 2730

Multiples of 445: 445, 890, 1335, 1780, 2225, 2670, 3115, 3560

So the LCM for 30 and 445 is 2670

Finding LCM for 30 and 445 by Prime Factorization
