How do you find the least common multiple of a list in python?
I have written a code to find out the LCM (Lowest Common Multiple) of a list of numbers but there appears to be an error in my code. The code is given below: Show
Kindly pardon my poor choice of variables, I request you to see if the logic is correct and that the code is functional. The syntax error which I am getting is that "factors" is invalid syntax though I don't agree with this. Please tell me where my code is wrong.

A faster approach without using any math functions would be to calculate GCD and calculate LCM.
Now find LCM using GCF
Extend this to work with list as below

YashwanthYashwanth 1661 silver badge9 bronze badges I had written a code to find lcm of numbers within a list. The User can input any number of values he wants. I'm attaching the code below, It is simpler than the code you posted. Try checking this... I know your question is to find errors in your code, but try checking this for future purpose.

This may be useful to you, Rather finding LCM directly, it is a bit simpler to derive LCM from GCD.

You're missing a bracket at the end of the line. Correct it to the following:
Also,
You need to indent the return statement because it is inside a conditional statement. And it is generally best practice to import any libraries you might need at the beginning rather than in the middle of a function. answered Sep 20, 2020 at 18:17

How do you find the least common multiple of a list?How to Find LCM by Listing Multiples. List the multiples of each number until at least one of the multiples appears on all lists.. Find the smallest number that is on all of the lists.. This number is the LCM.. How do you find the LCM in a for loop in Python?Step 1:Initially, Get 2 Integer Inputs from the user using int(input()). Step 2:Find the greater number by using an If condition and assign it to the variable 'max'. Step 3:Within the while loop, Use an If condition to check whether the remainder of (max% a) and (max% b) equals to zero or not.
What does LCM mean in Python?The Least Common Multiple (LCM) is also referred to as the Lowest Common Multiple (LCM) and Least Common Divisor (LCD). For two integers a and b, denoted LCM(a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b.
How do you find HCF and LCM in Python?Algorithm. Initialize HCF = 1.. Run a loop in the iteration of (i) between [1, min(num1, num2)]. Note down the highest number that divides both num1 & num2.. If i satisfies (num1 % i == 0 && num2 % i == 0) then new value of HCF is i.. Use lcm formula :- (num1*num2) / hcf.. Print the output.. |
