Minimum LCM will be when all four are equal. a = b = c = d = 1000/4 = 250.

LCM(a, b, c, d) = 250.

Since all numbers are equal, the LCM is one of the numbers.

Suppose one number, say "a" is decreased by x then one of b, c or d has to increase at least by 1. Then LCM will be more than 250.

<br />For such questions involving multiple integers , try a combination when all numbers are equal.

<br />Then try other combinations. You will get some understanding.
