What other number is like pi?
The value of e is approximately 2.71828 and, like Pi, is irrational and extends to infinity, a fact that the Swiss polymath Leonhard Euler proved about 20 years after its discovery.
What is special about the number 6174?
6174 is known as Kaprekar’s constant after the Indian mathematician D. R. Kaprekar. This number is notable for the following rule: Take any four-digit number, using at least two different digits (leading zeros are allowed).
What is the most popular number?
But if you ask enough people, you start to see which numbers emerge as consensus favorites across the population. Math blogger Alex Bellos recently did this, and after polling more than 44,000 people from around the world on his website, he got an answer: The world’s favorite number is 7.
What is Favourite number?
And the World’s Favorite Number Is… A survey launched by a British mathematics writer has found that seven is the world’s favorite number, reports The Guardian. The results of the online survey were published on Tuesday, with three, eight and and four coming second, third and fourth.
Why is 73 the best number?
Why? 73 is the 21st prime number. Its mirror (37) is the 12th and its mirror (21) is the product of multiplying 7 and 3. In binary, 73 is a palindrome, 1001001 which backwards is 1001001.”
Why is 1089 a magic number?
1089 is widely used in magic tricks because it can be “produced” from any two three-digit numbers. This allows it to be used as the basis for a Magician’s Choice. Take any three-digit number where the first and last digits differ by more than 1.
Why did Graham stop at 64?
To put it another way (in a similar fashion with G notation), you can define as (there are twelve arrows there), and for n > 1, we define as a , with arrows in between. “Little Graham” is equal to . He wasn’t able to show that dimensions was enough, but he could show sufficed, so that’s why the number stops at seven.
What is the rarest number?
If we consider palindromic rare numbers, there are infinitely many rare numbers. For example, the numbers in the series 242, 20402, 2004002, 200040002, 20000400002 … are palindromic rare numbers….Rare numbers.

Is Pi the most famous number in the world?
But no so fast … pi may be one of the most well-known numbers, but for people who are paid to think about numbers all day long, the circle constant can be a bit of a bore. In fact, countless numbers are potentially even cooler than pi.

How many digits of π are there in the world?
For all the digits of π that we can compute (the current record is about 12.1 trillion) and memorize (about 100,000) there will always be more beyond our grasp. This is because π is an irrational number, which means it cannot be written as the ratio of two whole numbers. Irrational numbers aren’t rare, though.
