How to write an equation with the available set of parameters?

Question

Mathematics

Please help me solve the problem!
x / y = z;
where z is a positive integer in the range [ 0 ; 1000 ],
x - any three-digit,
y - any, but not more than X.
It is necessary to find such a Y, in which Z, as a result of dividing X / Y, will always be a positive integer.

Answer 1

x can be a three-digit prime number, so only y = 1 satisfies the condition
