It's easy

36=2*3*6

so in the case of 72.hw its' come.its' came by twice of 36.

so it's easy 2 find out like u can twice any of those number(2*3*6) like (4*3*6)=72 or (2*6*6)=72 or (2*3*12)=72

so as much time u twice the number like 36-72-144-288 etc

u just hv 2 twice any of those number

@rakinasef It can be done for 225 also! So, something more generalized seems to exist there! And for 144, the options (3,6,8) and (4,4,9) can trick you. They are not part of the solution actually!! Be careful. In deed the problem is not valid for 144.

৯,২,২ হবে। কারণ ৯+২+২=১৩ আবার ৬+৬+১=১৩। কিন্তু যেহেতু বড়ো মেয়ে একটাই সেহেতু ৯,২,২ হবে।

আবার ৭২ এর ক্ষেত্রে দুইটা সম্ভাবনা। ৬+৬+২=১৪ আবার ৮+৩+৩=১৪। এখানেও বড়ো মেয়ে যেহেতু একটাই সেহেতু উত্তর হবে ৮,৩,৩। :)

চমক ভাইয়ের চমক তো নতুন নয়। তারপরও এই initiative টা দারুন লেগেছে।

I came up with a formula that covers most such numbers (and few extras :). The formula for any even number x is 2x^2(x+1)^2 and for any odd number x is x^2(x+1)^2/4. For instance, x=2 gives 72; x=3 gives 36; x=5 gives 225; x=7 gives 784; x=9 gives 2025. Not all x gives a valid number though. Few exceptions are 800 for x=4, 3528 for x=6, 10368 for x=8, 14400 for x=15 etc. Also, multiplying them by i^3 where i is positive integer gives more numbers. For (x,i)=(2,2)=>576=72*8; (3,3)=>972=36*27.
