The answer is 1152.

The relevant formula is best dealt with in two steps.

Step I: Find the LCM

I am not going to explain this step: there are many ways of finding the LCM. LCM(18, 24, 32) = 288.

Step II: Find multiple

The smallest 4-igit umber is 1000 so find the integer part of 1000/288. If there is no remainder then 1000 is the smallest 4-digit number. If there is (as is the case here) then the required answer is 288*[(quotient of 1000/288) + 1].
