• First, code a function to check if the input is prime
• Second, code a function to find and print all the prime factors in ascending order

For example:

12 = 2 * 2 * 3

19 = 19

2. Input & Output

Input:

• An integer N
• Use input() as input. Notice that the value you get from input() is a string

Output:

• A string like N = p1 * p2 * ...
• Prime factors are in ascending order
• Add one space between all the numbers, =, and *
• Use print() for your output

Example

# Input: 
1987
# Output: 
1987 = 1987

# Input: 
200
# Output: 
200 = 2 * 2 * 2 * 5 * 5
