Uniqueness of 153

 



Dear Friends

Wishing you a very happy Teatime

 

Numbers and human life are closely interconnected.

We think in numbers and live with numbers.

Our entire life is encircled by numbers.

 

In our life we come across some humans incredibly interesting

Likewise numbers are also interesting and incredible

 

People are interesting and incredible because

 

They are passionate. ...

They try new things. ...

They don't fit their life with norms and codes

They make their own path and make people follow them

They check their egos at the door. ...

They are always learning. ...

They share what they discover and find

They don't worry about what others think of them.

 

Likewise, there are some interesting numbers

They enjoy standing together with all the other numbers.

At the same time they stand alone and exhibit their speciality

 

Let us see their uniqueness.

 

One such number is 153

 

Add the sum of the digits.

 1+5+3=9

So the number is divisible by 9

Its other divisors are 1, 3, 17, 51, and 153.

Add all divisors: 1+3+9+17+51+153=234

Which is half of 153.

 

 

153 = 13 + 53 + 33

 

153 is a triangular number

Add first 17 numbers

1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17=153

 

We can get 153 from 108

 

13 + 03 + 83 = 513 and

53 + 13 + 33 = 153

 

Like 153 there are   other numbers too.

They are indicated in the picture above

They are called Armstrong Numbers

 

 

Kind Regards

Happy Evening
