What's the Least Common Multiple (LCM) of 90 and 315?

Answer

LCM of 90 and 315 is 630

(Six hundred thirty)

Finding LCM for 90 and 315 using GCF of these numbers

The first method to find LCM for numbers 90 and 315 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 90 and 315 is 45, so

LCM = (90 × 315) ÷ 45

LCM = 28350 ÷ 45

LCM = 630

Finding LCM for 90 and 315 by Listing Multiples

The second method to find LCM for numbers 90 and 315 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

Multiples of 315: 315, 630, 945, 1260

So the LCM for 90 and 315 is 630

Finding LCM for 90 and 315 by Prime Factorization

Another method to find LCM for numbers 90 and 315 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 315: 3, 3, 5, 7 (exponent form: 32, 51, 71)

21 × 32 × 51 × 71 = 630
