Thank you sir, & how to find out if a & b are non primes ??

If a or b is composite, we simply break them down into prime numbers again. Example: 100 = 50 × 2 Here 50 is composite. 50 is broken down into 25 and 2, and 25 is again broken down into 5×5. 100 = 5² × 2²
Very nice sir... From where you get these tricks ?please tell us your secret.

Sum of divisors ?
Thanks for sharing this, Sir, however, I just found out that there is an error for 8 which is 2^3 if I use x=a^m * b^n That's correct if we use 8=2^3 * 2^0, then the number of divisors is right, (3+1) (0+1) which is 4, however if we use m=2 and n=1, for a=b which is 2, the number of divisors is 6, which is wrong because we want 4 which is the right answer So, I guess that we have to use the a^m first until the number mod a is not zero anymore (that is, a result with the number behind a comma instead of zero), then b^n until the number mod b is not zero anymore, and so on

show the proof sir...
The sequence of triangle numbers is generated by adding the natural numbers. So the 7th triangle number would be 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28. The first ten terms would be: 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ... What is the value of the first triangle number to have over five hundred divisors?
