## Getting the maximum and the minimum with now

In the following cryptarithmetic equation, each of the x’s represent a decimal digit, whether same or different, and “NOW” represents a three digit positive integer with no leading zero. Each of N, O and W represent a decimal digit, whether same or different.

(N O W) * (N O W)
= (x x x x x x N O W)/1983

What are the respective minimum value and the maximum value of “NOW”?

 Blog Entries: 1 Recognitions: Gold Member Spoiler There are three values of NOW that satisfy the equation: 272: 272 * 272 == 146710272 / 1983 375: 375 * 375 == 278859375 / 1983 647: 647 * 647 == 830101647 / 1983 272 is the minimum and 647 is the maximum. This was found by brute force.
