LCM for 5 and 180
What's the Least Common Multiple (LCM) of 5 and 180?
(One hundred eighty)
Finding LCM for 5 and 180 using GCF's of these numbers
The first method to find LCM for numbers 5 and 180 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 5 and 180 is 5, so
LCM = (5 × 180) ÷ 5
LCM = 900 ÷ 5
LCM = 180
Finding LCM for 5 and 180 by Listing Multiples
The second method to find LCM for numbers 5 and 180 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
Multiples of 180: 180, 360, 540, 720, 900, 1080, 1260, 1440, 1620, 1800, 1980, 2160, 2340, 2520, 2700, 2880, 3060, 3240, 3420, 3600, 3780, 3960, 4140, 4320, 4500, 4680, 4860, 5040, 5220, 5400, 5580, 5760, 5940, 6120, 6300, 6480, 6660, 6840, [...], 180
So the LCM for 5 and 180 is 180
Finding LCM for 5 and 180 by Prime Factorization
Another method to find LCM for numbers 5 and 180 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 180: 2, 2, 3, 3, 5 (exponent form: 22, 32, 51)
51 × 22 × 32 = 180
