You are a number less than 100 two of your factors are 3 and 5 your digits are 1 apart what number are you?

You are 45. Remember, if a number is divisible by 5, then it must either end in 0 or 5. Therefore, since your digits are one apart, your only possibilities are 10, 45, and 65. Now, if a number is divisible by 3, the digits of that number add up to a number that is divisible by three. Of your three possibilities, this only works with 45 since 4 + 5 = 9 and 9 is divisible by 3. Hence, you are 45.
