Lecture 52:-  LCM In Python

In Python, you can find the least common multiple (LCM) of two or more numbers using the math.lcm() function from the math module. The LCM is the smallest positive integer that is divisible by all the numbers.

Here's an example of how to find the LCM of two numbers:

pythonCopy code

import math def find_lcm(a, b):    return math.lcm(a, b) # Example usage: num1 = 12 num2 = 18 lcm_result = find_lcm(num1, num2) print(f"The LCM of {num1} and {num2} is: {lcm_result}")

Output:

csharpCopy code

The LCM of 12 and 18 is: 36

In this example, the find_lcm() function takes two numbers a and b as input and uses the math.lcm() function to calculate their LCM. The function returns the LCM as the result.

To find the LCM of more than two numbers, you can call the math.lcm() function multiple times, passing the result of the previous LCM calculation and the next number as arguments.

pythonCopy code

import math def find_lcm(*args):    result = args[0]    for num in args[1:]:        result = math.lcm(result, num)    return result # Example usage: num1 = 12 num2 = 18 num3 = 24 lcm_result = find_lcm(num1, num2, num3) print(f"The LCM of {num1}, {num2}, and {num3} is: {lcm_result}")

Output:

csharpCopy code

The LCM of 12, 18, and 24 is: 72

In this example, the find_lcm() function uses variable-length arguments (*args) to accept any number of input arguments. It then iterates through each argument, calculating the LCM one by one and updating the result. The final result is the LCM of all the input numbers.
