What's the Least Common Multiple (LCM) of 90 and 305?

Answer

LCM of 90 and 305 is
5,490

(Five thousand four hundred ninety)

Finding LCM for 90 and 305 using GCF of these numbers

The first method to find LCM for numbers 90 and 305 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 90 and 305 is 5, so

LCM = (90 × 305) ÷ 5

LCM = 27,450 ÷ 5

LCM = 5,490

Finding LCM for 90 and 305 by Listing Multiples

The second method to find LCM for numbers 90 and 305 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, 2790, 2880, 2970, 3060, 3150, 3240, 3330, 3420, 3510, 3600, 3690, 3780, 3870, 3960, 4050, 4140, 4230, 4320, 4410, 4500, 4590, 4680, 4770, 4860, 4950, 5040, 5130, 5220, 5310, 5400, 5490, 5580, 5670

Multiples of 305: 305, 610, 915, 1220, 1525, 1830, 2135, 2440, 2745, 3050, 3355, 3660, 3965, 4270, 4575, 4880, 5185, 5490, 5795, 6100

So the LCM for 90 and 305 is 5,490

Finding LCM for 90 and 305 by Prime Factorization

Another method to find LCM for numbers 90 and 305 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)
