Hello everyone, welcome back to programminginpython.com. Here I am going to tell a simple logic by which we can find the LCM of two numbers in python.
LCM means Least Common Multiple, for a given 2 numbers we need to find the least common multiple for them.
Let’s take an example of 3 and 5, here I will find the LCM of those 2 numbers.
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24…
Multiples of 5: 5, 10, 15, 20, 25, 30….
Now we find the first number which is found in both the multiples and it is clear that 15 is that number, and the LCM(3, 5) will be 15.

Task
To find LCM of 2 numbers
Approach
- Read two input numbers using
input(). - Find the minimum of 2 numbers, using
min()function and store the value innumbers_minvariable. - Now run a while loop and check whether both numbers are divisible by the
numbers_minvariable which we got in the previous step.- if both numbers are divisible by
numbers_minprint the value as LCM and break the loop - if not, increment
numbers_minvalue and continue while loop.
- if both numbers are divisible by
