What's the Least Common Multiple (LCM) of 30 and 270?

Answer

LCM of 30 and 270 is 270

(Two hundred seventy)

Finding LCM for 30 and 270 using GCF of these numbers

The first method to find LCM for numbers 30 and 270 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 30 and 270 is 30, so

LCM = (30 × 270) ÷ 30

LCM = 8100 ÷ 30

LCM = 270

Finding LCM for 30 and 270 by Listing Multiples

The second method to find LCM for numbers 30 and 270 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

Multiples of 270: 270, 540, 810

So the LCM for 30 and 270 is 270

Finding LCM for 30 and 270 by Prime Factorization

Another method to find LCM for numbers 30 and 270 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 30: 2, 3, 5 (exponent form: 21, 31, 51)

All Prime Factors of 270: 2, 3, 3, 3, 5 (exponent form: 21, 33, 51)

21 × 33 × 51 = 270
