Math Genius

I do not know if the following is true, but someone attributed this to Hazrat Ali ibn Abi-Taalib (May Allah be pleased with him) as a Math Genius:

One Day a person came to Hazrat Ali (May Allah be pleased with him), thinking that people say "Ali is too smart;" I'll ask him such a tough question that he won't be able to answer and I'll embarrass him in front of all Arabs.

He asked, "Ali, can you tell me a number, that if we divide it by any number from 1-10 the answer will always come in the form of a whole number and not as a fraction." Ali Looked back at him and said, "Take the number of months in a year, multiply it with number of days in a month (30), and multiply that with the number of days in a week and you will have your answer." The person did not believe Ali. He checked the answer and found it was correct. The number was 12 x 30 x 7 = 2520

A person was about to die, and before dying he wrote his Will, "I have 17 Camels, and I have three sons. Divide my Camels in such a way, that My eldest son gets half of them, the second one gets 1/3rd of the total and my youngest son gets 1/9th of the total number of Camels."

After his death when the relatives read his will they got extremely perplexed and said to each other that how can we divide 17 camels like this.

So after a long hard thought they decided that there was only one man in Arabia who could help them: "Ali Ibn Abi- Taalib (May Allah be pleased with him)." So they all came to him and put forward their problem. Ali(May Allah be pleased with him) said, "Ok. I will divide the camels as per the man's will; I will lend one of my camels to the total which makes it 18; now lets divide as per his will."
The Eldest gets 1/2 of 18 = 9
The second one gets 1/3 of 18 = 6
and The Youngest gets 1/9 of 18 = 2

That distributes 17 camels.

Then Ali (May Allah be pleased with him) said, "Now I will take my Camel back." subhanAllah...
