Multiplicative Digital Root Of A Number Using Loops

I need to find the multiplicative digital root of a number in python using only loops. something that does the same as the below code but using loops: print('multiplicative digital

Solution 1:

Basically, you're looking for something like this:

number = 9876; #Example
divider = 1;
digits = []
answer = -1
while true:
    value = 1
    while number % divider != 0: #Fills list with digits
        digits.append(number % divider)
        divider = divider * 10
    while list.len() != 0: # Empty list for next iteration
        value = value * list[0]
        list.remove(0) # The elements will always be 0, as the first one is constantly removed
    number = value # Change for next iteration
    if value == value % 10: # If there's only a single digit left, you've got it
        answer = value # Finish up, close
        break

Solution 2:

def d_root(num):

   temp=num

   c=0

   while 1:

      p=1

      c=c+1

      while temp!=0:

         rem=temp%10

         p=p*rem

         temp=int(temp/10)

      if p<10:

         print("Multiplicative Presistance ",c)

         print("Multiplicative Digital Root ",p)

         break

      temp=p

n=int(input("Enter any Number "))

d_root(n)

Solution 3:

def digital_root(num):

   temp=num
   while(1):
      p=1
      while temp!=0:
         rem=temp%10
         p=p*rem
         temp=int(temp/10)
      if p<10:
         print(p)
         break
      temp=p
num=int(input("Enter number"))
digital_root(num)
