None. The greatest common multiple of any set of integers is infinite.
The greatest number that is a multiple of both 2 and 5 is their least common multiple (LCM), which is 10. Since you are looking for the greatest number of 3, you can find the largest multiple of 10 that is less than or equal to 3, which is 0. Therefore, the greatest number of 3 that is divisible by both 2 and 5 is 0.
