Three of them.
Oh, what a happy little question! Let's paint a picture with numbers. The numbers less than 70 that are multiples of both 3 and 5 are 15, 30, 45, and 60. Just like when we add different colors to our canvas, these numbers come together in perfect harmony. Keep up the beautiful work, my friend!
Odd multiples of 7 less than 50 are numbers that are both odd and divisible by 7, and are less than 50. The odd multiples of 7 less than 50 are 7, 21, and 35. These numbers are odd because they are not divisible by 2, and they are multiples of 7 because they can be divided evenly by 7.
As numbers get larger, it is more likely that they will be multiples of something.
There are 3 such numbers: 30, 60, 90.
When one of the numbers is positive and the other is negative.
All nonzero numbers have an infinite amount of multiples.

Squares numbers are positive numbers. So that the square numbers less than 100 are 1, 4, 9, 16, 25, 36, 49, 64, and 81, and only 16 and 64 are multiples of 8. Thus, Greta picked 16, and 64.
There are eleven such numbers.Get the common multiple of those numbers. All other common multiples will be multiples of this common multiple; that is, you can multiply the common multiple by 1, by 2, by 3, etc. to get additional numbers that are multiples of both numbers.
Odd multiples of 7 less than 50 are numbers that are both odd and divisible by 7, and are less than 50. The odd multiples of 7 less than 50 are 7, 21, and 35. These numbers are odd because they are not divisible by 2, and they are multiples of 7 because they can be divided evenly by 7.
15, 30, 45, 60
109 whole numbers greater than 9 and less than 999 are multiples of 9
As numbers get larger, it is more likely that they will be multiples of something.
3. All other multiples of 3 are not prime.
There are 3 such numbers: 30, 60, 90.
When one of the numbers is positive and the other is negative.
-- both are positive numbers -- both are greater than 15 -- both are less than 1 googol -- both are even numbers -- both are written with one odd digit and one even digit -- both are powers of 2 -- both have the factors (are multiples of) 1, 2, 4, 8, and 16
