LCM is the lowest multiple of two or more numbers. Multiples of a number are those numbers which when divided by the number leave no remainder. When we are talking about the multiple, we consider only the positive number. For example, the LCM of 12 and 48 is 48 because 48 is 4th multiple of 12 and 48 is 1st multiple of 48. Here, an array of positive elements will be provided by the user and we have to find the LCM of the elements of the array by using the Python. To find LCM of the elements of the array, use the following algo,
Algorithm to find the LCM of array elements
- We need to import the math module to find the GCD of two numbers using math.gcd() function.
- At first, find the LCM of initial two numbers using: LCM(a,b) = a*b/GCD(a,b). And, then find the LCM of three numbers with the help of LCM of first two numbers using LCM(ab,c) = lcm(lcm(a1, a2), a3). The same concept we have implemented.
