Answer: LCM of 15 and 39 is 195

(One hundred ninety-five)

Finding LCM for 15 and 39 using GCF's of these numbers

The first method to find LCM for numbers 15 and 39 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 15 and 39 is 3, so

LCM = (15 × 39) ÷ 3

LCM = 585 ÷ 3

LCM = 195

Finding LCM for 15 and 39 by Listing Multiples

The second method to find LCM for numbers 15 and 39 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, 210, 225

Multiples of 39: 39, 78, 117, 156, 195, 234, 273

So the LCM for 15 and 39 is 195

Finding LCM for 15 and 39 by Prime Factorization

Another method to find LCM for numbers 15 and 39 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 39: 3, 13 (exponent form: 31, 131)

31 × 51 × 131 = 195
