Finding LCM for 2 and 15 using GCF's of these numbers
The first method to find LCM for numbers 2 and 15 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 2 and 15 is 1, so
LCM = (2 × 15) ÷ 1
LCM = 30 ÷ 1
LCM = 30
Finding LCM for 2 and 15 by Listing Multiples
The second method to find LCM for numbers 2 and 15 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34
Multiples of 15: 15, 30, 45, 60
So the LCM for 2 and 15 is 30
Finding LCM for 2 and 15 by Prime Factorization
Another method to find LCM for numbers 2 and 15 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 2: 2 (exponent form: 21)
All Prime Factors of 15: 3, 5 (exponent form: 31, 51)
21 × 31 × 51 = 30
