Python Program for nth multiple of a number in Fibonacci Series

In this article, we will learn about the solution to the problem statement given below.

Problem statement− We are given a number, we need to find the nth multiple of a number k in Fibonacci number.

The solution to the problem is discussed below−

Example

# find function
def find(k, n):
   f1 = 0
   f2 = 1
   i =2;
   #fibonacci recursion
   while i!=0:
      f3 = f1 + f2;
      f1 = f2;
      f2 = f3;
      if f2%k == 0:
         return n*i
      i+=1
   return
# multiple of which number
n = 5;
# number
k = 4;
print("Position of n\'th multiple of k in""Fibonacci Series is: ", find(k,n));

Output

Position of n'th multiple of k inFibonacci Series is:  30

All the variables and functions are declared in the global scope as shown in the figure above.

Conclusion

In this article, we have learned how we can find nth multiple of a number k in the Fibonacci series.
