If the LCM of the first 10 natural numbers is N, what would be the LCM of the first 20 natural numbers?

The LCM (Least Common Multiple) of a set of numbers is the smallest number that is a multiple of all the numbers in the set.

Step 1: Find the LCM of the first 10 natural numbers.

The first 10 natural numbers are: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

The LCM of these numbers is 2520.

Step 2: Find the LCM of the first 20 natural numbers.

The first 20 natural numbers are: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20.

The LCM of these numbers is 232792560.

So, if the LCM of the first 10 natural numbers is N (which is 2520), the LCM of the first 20 natural numbers is 232792560.
