Finding LCM for 6 and 5 using GCF of these numbers
The first method to find LCM for numbers 6 and 5 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 6 and 5 is 1, so
LCM = (6 × 5) ÷ 1
LCM = 30 ÷ 1
LCM = 30
Finding LCM for 6 and 5 by Listing Multiples
The second method to find LCM for numbers 6 and 5 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 6: 6, 12, 18, 24, 30, 36, 42
Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40
So the LCM for 6 and 5 is 30
Finding LCM for 6 and 5 by Prime Factorization
Another method to find LCM for numbers 6 and 5 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 6: 2, 3 (exponent form: 21, 31)
All Prime Factors of 5: 5 (exponent form: 51)
21 × 31 × 51 = 30
