Is it there before that.. If no one realised then credit goes to me.. Starting from 48

Fifty-three is the 16^th prime number. It is also an Eisenstein prime.

The sum of the first 53 primes is 5830, which is divisible by 53, a property shared by few other numbers.^[1][2]

53 written in hexadecimal is 35, that is, the same characters used in the decimal representation, but reversed. At least four multiples of 53 share this property: 371 = 173₁₆, 5141 = 1415₁₆, 99481 =18499₁₆, and 8520280 = 820258₁₆.

53 can not be expressed as the sum of any integer and its base 10 digits, making 53 a self number.

54 is a 19-gonal number. Twice the third power of three, 54 is a Leyland number. 54 can be written as the sum of three squares in three different ways: . It is the smallest number with this property. Like all other multiples of 6, it is a semiperfect number.

The factorial of 54 is 230,843,697,339,241,380,472,092,742,683,027,581,083,278,564,571,807,941,132,288,000,000,000,000, or approximately 230.843697339241 x 10⁶⁹.

In base 10, 54 is a Harshad number.

That's none of your business.. There would be a 1000 things between me and my ex you don't interfere 😆

Fifty-five has the interesting property that it is the 10th Fibonacci number and the sum of the numbers 1 to 10.

It is a heptagonal number, a centered nonagonal number, and a triangular number (the sum of the numbers 1 to 10) and a square pyramidal number (the sum of the squares of the integers 1 to 5). It is also a Fibonacci number (the largest Fibonacci number to also be a triangular number) and a Kaprekar number.

55 is a semiprime, being the product of 5 and 11 and it is the 2nd member of the (5.q) semiprime family. 55 is one of only two integers with an aliquot sum of 17 (the other being 39). 55 has an aliquot sequence of 4 members: (55, 17, 1, 0).
