Is there a number that is both prime and a multiple of 3?
Of course. There is 3. Remember, multiples of 3 can also be divided by 3, so the only prime number that is a multiple of 3 is 3.
What is the smallest number that is a multiple of both 3 and 6?

What number is both a prime number and a multiple of 3?
No number that is a multiple of 3, can be a prime number. A prime number must only be divisible by itself and 1. It cannot be divisible by any other number. Therefore if it is a multiple of 3, then it must be divisible by 3 and hence, not a prime number.
How do you find a multiple?
A multiple of a number is something you get when you multiply that number by another. For instance, 5 x 2 = 10, so 10 is a MULTIPLE of 5 and a MULTIPLE of 2. If you're trying to find a multiple of a number, say, 3, multiply that number by another. It can be any number.
Is 19 a multiple of 3?
No. To check if a number is a multiple of 3 add its digits together and if this sum is a multiple of 3, then so is the original number. This sum can be continued until a single digit remains; if the single digit is 3, 6 or 9 then the original number is a multiple of 3, otherwise not. 19 → 1 + 9 = 10 10 → 1 + 0 = 1 which is not 3, 6 or 9, so 19 is not a multiple of 3.
