Hi Brilliant folks,

I made a website http://math-utilities.com/, for the sake of this community. Feel free to head over to that page, and make use of it.
I love this problem solvers community and felt its my bit to help others along their journey.

Thanks a lot! Any cheers and blessings are much appreciated.

How to find last three digits of 7^999 without using Euler's function or by using it also. Will it be true for all primes like 13^999 or any other. Please let me know it. And about this website, it is a good one.

@Siva Bathula Good work!

Thanks for it.

Neat website!

Why do you think that this function does not always work?

What if there are multiple real roots between the "Start" and "End"?

The remainder finding algorithm fails in certain cases. I am not yet sure if it is closer to 100% but I have improved it to cut down some border cases. The polynomial eq. solver gives all real roots between Start and End. Thanks a lot for the neat comment! Looking forward for more positive feedback.

Your "bisection method" section might be flawed.

I've submitted

`1,3,3,1`

for the coefficients, and the range between -10 and 10.The answer spits out -1.007937, but it should be just -1 (with a multiplicity of 3).

Plus, you might want to add a function to find the multiplicity of the roots.

Your "Cubic equation solver" might be flawed as well.

I've submitted

`1,3,3,1`

for the coefficients as well, and it outputs: NaN for all x1, x2, x3.Your GCD and LCM are flawed too.

If I submit "-2, -4" in GCD, it should spit out 2, not -2.

If I submit "-2, -1, -3" in LCM, it should spit out 6, not -6.
