What's the Least Common Multiple (LCM) of 90 and 280?

Answer

LCM of 90 and 280 is 2,520

(Two thousand, five hundred twenty)

Finding LCM for 90 and 280 using GCF of these numbers

The first method to find LCM for numbers 90 and 280 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 90 and 280 is 10, so

LCM = (90 × 280) ÷ 10

LCM = 25200 ÷ 10

LCM = 2520

Finding LCM for 90 and 280 by Listing Multiples

The second method to find LCM for numbers 90 and 280 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 90: 90, 180, 270, 360, 450, 540, 630, 720, 810, 900, 990, 1080, 1170, 1260, 1350, 1440, 1530, 1620, 1710, 1800, 1890, 1980, 2070, 2160, 2250, 2340, 2430, 2520, 2610, 2700

Multiples of 280: 280, 560, 840, 1120, 1400, 1680, 1960, 2240, 2520, 2800, 3080

So the LCM for 90 and 280 is 2520

Finding LCM for 90 and 280 by Prime Factorization

Another method to find LCM for numbers 90 and 280 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 90: 2, 3, 3, 5 (exponent form: 21, 32, 51)

All Prime Factors of 280: 2, 2, 2, 5, 7 (exponent form: 23, 51, 71)

23 × 32 × 51 × 71 = 2520
