Smallest Multiple
You are given a positive integer N. Your task is to find the smallest positive integer that is divisible by each of the numbers from 1 to N.
You can think of the problem as finding the least common multiple (LCM) for the set \(\{1, 2, \dots, N\}\). The LCM for two numbers a and b is given by the formula:
\( \text{lcm}(a,b) = \frac{|a \times b|}{\gcd(a,b)} \)
For example, if N = 4, the numbers are 1, 2, 3, and 4. The smallest multiple that is divisible by all these numbers is 12.
Input/Output Specifications:
- Input: A single integer N.
- Output: The smallest positive integer that is divisible by every number from 1 to N.
inputFormat
