LCM for 5 and 65
What's the Least Common Multiple (LCM) of 5 and 65?
(Sixty-five)
Finding LCM for 5 and 65 using GCF's of these numbers
The first method to find LCM for numbers 5 and 65 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 5 and 65 is 5, so
LCM = (5 × 65) ÷ 5
LCM = 325 ÷ 5
LCM = 65
Finding LCM for 5 and 65 by Listing Multiples
The second method to find LCM for numbers 5 and 65 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75
Multiples of 65: 65, 130, 195, 260, 325, 390, 455, 520, 585, 650, 715, 780, 845, 910, 975, [...], 65
So the LCM for 5 and 65 is 65
Finding LCM for 5 and 65 by Prime Factorization
Another method to find LCM for numbers 5 and 65 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 5: 5 (exponent form: 51)
All Prime Factors of 65: 5, 13 (exponent form: 51, 131)
51 × 131 = 65
