What's the Least Common Multiple (LCM) of 15 and 33?

Answer: LCM of 15 and 33 is 165

(One hundred sixty-five)

Finding LCM for 15 and 33 using GCF's of these numbers

The first method to find LCM for numbers 15 and 33 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 15 and 33 is 3, so

LCM = (15 × 33) ÷ 3

LCM = 495 ÷ 3

LCM = 165

Finding LCM for 15 and 33 by Listing Multiples

The second method to find LCM for numbers 15 and 33 is to list out the common multiples for both nubmers and pick the first which matching:

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

Multiples of 33: 33, 66, 99, 132, 165, 198, 231

So the LCM for 15 and 33 is 165

Finding LCM for 15 and 33 by Prime Factorization

Another method to find LCM for numbers 15 and 33 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 33: 3, 11 (exponent form: 3¹, 11¹)

3¹ × 5¹ × 11¹ = 165
