Answer:
Multiples of 60
Step-by-step explanation:
If a a number finished with a 0, (unless it is 0) than it is divisible by 2 and 5.
If a number is divisible by 20 then it is divisible by 4. Finally if its divisible by 6 then it is by 3 too.
60 is the first number that satisfies all of the constraints and so does any of its multiples (up to 180 in this case)
