What's the Least Common Multiple (LCM) of 5 and 39?
(One hundred ninety-five)
Finding LCM for 5 and 39 using GCF's of these numbers
The first method to find LCM for numbers 5 and 39 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 5 and 39 is 1, so
LCM = (5 × 39) ÷ 1
LCM = 195 ÷ 1
LCM = 195
Finding LCM for 5 and 39 by Listing Multiples
The second method to find LCM for numbers 5 and 39 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, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150, 155, 160, 165, 170, 175, 180, 185, 190, 195, 200, 205
Multiples of 39: 39, 78, 117, 156, 195, 234, 273
So the LCM for 5 and 39 is 195
Finding LCM for 5 and 39 by Prime Factorization
Another method to find LCM for numbers 5 and 39 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 39: 3, 13 (exponent form: 31, 131)
51 × 31 × 131 = 195
