LCM( 5, 8, 1 ) = 40
Step 1 : Place the numbers inside division bar:
5 | 8 | 1 |
Step 2 : Find a prime number which can divide at least two of your numbers.
Since there are no primes that divides at least two of given numbers, we conclude that the LCM is a product of starting numbers.
LCM = 5 · 8 · 1 = 40
This solution can be visualized using a Venn diagram.
The LCM is equal to the product of all the numbers on the diagram.
