Also, the number I'm going for has to follow these rules: -It ends in 0, making it divisible by 2, 5, and 10. -The two digits before the zero will form a number divisible by 4, resulting in it being divisible by 4, 8, 20, and 40. -The sum of the digits is 9, making it divisible by 3, 6, 9, and 18. (6 and 18 because it's even)
