Built-in module to calculate the least common multiple
This is available as math.lcm(). It also takes any number of arguments, allowing you to find the lowest common multiple of more than 2 integers. For example: >>> from math import lcm. >>> lcm(2, 5, 7) 70. edited May 8, 2022 at 15:37.

C++ algorithm to calculate least common multiple for multiple numbers
let the set of numbers whose lcm you wish to calculate be theta. let i, the multiplier, be = 1. let x = the largest number in theta. x * i. if for every element j in theta, (x*i)%j=0 then x*i is the least LCM. if not, loop, and increment i by 1.

How to find the least common multiple of a range of numbers?
As this question has recently been revived, here's what I think is a simpler take on the question, writing very simple helper functions to calculate the greatest common divisor of two integers (gcd), to calculate the least common multiple of two integers (lcm), to calculate the least common multiple of an array of integers (lcmAll), to generate the range of integers between two given integers ...

Calculate the LCM of a list of given numbers in Python
Return the least common multiple of the specified integer arguments. If all arguments are nonzero, then the returned value is the smallest positive integer that is a multiple of all arguments. If any of the arguments is zero, then the returned value is 0. lcm() without arguments returns 1. Advantages: Besides being native, Its a one-liner, Its ...

c# - Least Common Multiple - Stack Overflow
Here's a more efficient and concise implementation of the Least Common Multiple calculation which takes advantage of its relationship with the Greatest Common Factor (aka Greatest Common Divisor). This Greatest Common Factor function uses Euclid's Algorithm which is more efficient than the solutions offered by user1211929 or Tilak. C#, C++, C:

What is the most efficient way to calculate the least common multiple ...
Remember The least common multiple is the least whole number that is a multiple of each of two or more numbers. If you are trying to figure out the LCM of three integers, follow these steps: **Find the LCM of 19, 21, and 42.** Write the prime factorization for each number. 19 is a prime number. You do not need to factor 19.

Least common multiple for more than two numbers
I want to find out Least Common Multiple (LCM) of more than two numbers. I know the formula of lcm (a,b) = (a * b) / gcd (a,b). Let's say, I have an array of numbers: [2, 6, 8, 13] and the the lcm should be modulo M = 1000000007. I have seen below code to calculate the LCM of multiple numbers but I am not understanding how the calculation is ...

Least common multiple for 3 or more numbers - Stack Overflow
But have no idea how to expand it to calculate 3 or more numbers. So far this is how I did it. LCM = num1 * num2 / gcd ( num1 , num2 ) With gcd is the function to calculate the greatest common divisor for the numbers. Using euclidean algorithm. But I can't figure out how to calculate it for 3 or more numbers. algorithm.

How to find GCD, LCM on a set of numbers - Stack Overflow
return a; // or return b, a will be equal to b either way. // the lcm is simply (a * b) divided by the gcf of the two. return (a * b) / gcf(a, b); This is an implementation of the Euclidean Algorithm. To find the GCF of two numbers, subtract the larger number from the smaller number while the two numbers are not equal.
