I code a program to solve puzzle but i can't make it more dynamic.

There is no reason to test every value. If the result must be divisible for all numbers 1 through 9, the number will be divisible by 9. There is no reason to test 17 or 33 or 121.

def find_number(first, last):
    """Find first number that is divisible by all numbers in range first..last"""
    num = last
    while True:
        for divisor in range(first, last):
            if num % divisor != 0: # Failed test.  Try next num
                num += last
                break # break out of for loop
        else: # Gets called if for loop reaches end
            print(num)
            break;  # Break out of while loop

find_number(5, 13)
