What's the Least Common Multiple (LCM) of 15 and 36?

Answer

LCM of 15 and 36 is 180

(One hundred eighty)

Finding LCM for 15 and 36 using GCF of these numbers

The first method to find LCM for numbers 15 and 36 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 15 and 36 is 3, so

LCM = (15 × 36) ÷ 3

LCM = 540 ÷ 3

LCM = 180

Finding LCM for 15 and 36 by Listing Multiples

The second method to find LCM for numbers 15 and 36 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 15: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210

Multiples of 36: 36, 72, 108, 144, 180, 216, 252

So the LCM for 15 and 36 is 180

Finding LCM for 15 and 36 by Prime Factorization

Another method to find LCM for numbers 15 and 36 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 15: 3, 5 (exponent form: 31, 51)

All Prime Factors of 36: 2, 2, 3, 3 (exponent form: 22, 32)

32 × 51 × 22 = 180
