There are 278 5-digit numbers less than 20,000 that are divisible by both four and nine.
1008 is the lowest four-digit number divisible by 36, and 9972 is the highest.
The lowest 4-digit number that is divisible by 6 is 1002
The trick to this question is to realize that you can tell a number is divisible by nine by observing whether the sum of it's digits is divisible by nine.For example, we know that the number 25731 is divisible by nine, because 2 + 5 + 7 + 3 + 1 = 18, and 18 is divisible by nine.So in this case, what we want is a value for "A" in which 3 + A + A + 1, or 2A + 4, is divisible by 9. "A" also has to be less than ten (as we're dealing with a specific digit). That leaves us with only one possible digit, 7. 3 + 7, + 7 + 1 = 18, and 18 is indeed divisible by nine, so we know that 3771 is also divisible by nine.
144 is divisible by 12 and 9.
