Mathematics can be tricky most of the time. This is a subject which is fun for some people and for some it’s the world’s hardest thing to solve. But sometimes some topics just create curiosity in everyone’s mind whether you like mathematics or not.

So, today I’m going to tell you about a topic which leaves you too in curiosity as it’s said in mathematics there is no such number which can be divided by the digits from 1 to 10 but it was only applicable till the great Mathematician Srinivasa Ramanujan discovered a number which was divisible by all the digits from 1 to 10 and this number and his discovery had left most of the mathematicians around the world in perplexed.

## Who is Srinivasa Ramanujan?

Srinivasa Ramanujan was born in Erode, Tamil Nadu, India on 22nd December 1887 he was known as India’s mathematics genius. While in his childhood he did so well in studies and made himself an able all-rounder scholar and at an early age started working on his mathematics on the topics of arithmetic series and summing geometry. To sum up, Srinivasa Ramanujan outnumbered mathematics.

## What is that unique number?

The unique number that Srinivasa Ramanujan discovered was ‘2520’. Now that’s where all the mystery ends this is the number which can be divided by all the digits 1,2,3,4,5,6,7,8,9,10 and it is to be said that after Ramanujan no one could ever find another number that’s divisible by all these digits. That’s the reason this number is known as the most unique number.

Now you may think that 2520 is just a simple number and it’s like every other number but in reality, it’s not. That’s the reason why all the greatest mathematicians were shocked to see the results from this number.

## What’s the secret behind this unique number?

I know you all were waiting for this part so here we go. This number 2520 is divisible from all the numbers 1 to 10 whether the number is odd or even leaving zero for obvious reasons.

Let’s see this table and whether all of this is true:

• 2520 ÷ 1 = 2520
• 2520 ÷ 2 = 1260
• 2520 ÷ 3 = 840
• 2520 ÷ 4 = 630
• 2520 ÷ 5 = 504
• 2520 ÷ 6 = 420
• 2520 ÷ 7 = 360
• 2520 ÷ 8 = 315
• 2520 ÷ 9 = 280
• 2520 ÷ 10 = 252

Now, what’s the first thing that came into your mind? Maybe this was so easy and it is but that’s its uniqueness that only this number is divisible from 1 to 10 and discovering about this is also not easy that’s the reason no one could ever find or discover any such number which was possibly divisible by all these digits.

## What made this possible?

What’s that one thing which makes this number possible to be divisible? A very simple answer is – ‘Time’ the perfect dominance. And if I say the magic behind this number can be explained with the help of multiplication would all of you agree? Okay, let’s see the explanation of this riddle. You just have to keep in mind the Indian Hindu Year.

Considering there are 7 days in a whole week, 30 days in a month, and a total of 12 months in a year. So, if we multiply all these three numbers i.e. 7 × 30 × 12 = 2520. Surprised? That’s the sharpness of Srinivasa Ramanujan, what a great man!!

## Conclusion

In particular, India has made important discoveries in many areas of mathematics whether you take Aryabhatta’s discoveries or Srinivasa Ramanujan’s discoveries. This was one of his famous works but he has also contributed to the analytical theory of numbers, infinite series, continued fractions, and elliptic functions.
