Step 1 : Write the given numbers in a horizontal line.

Step 2 : Divide the given numbers by smallest prime number. In this example we can divide by 2.

(if any number is not divisible by 2, write it down unchanged)

Step 3 : Continue dividing by prime numbers till we get 1 in all columns.

Step 4 : Multiply numbers in first column to get LCM.

LCM( 50982, 1758 ) = 2 · 3 · 29 · 293 = 50982 .

This solution can be visualized using a Venn diagram.

The LCM is equal to the product of all the numbers on the diagram.
