Happy Perfect Number Day!

Today is Perfect Number Day!

A Perfect Number is a number whose factors add up to the same number.

For example, 6 is a Perfect Number because the factors of 6 (= 1+2+3) add up to 6.

The next Perfect number is 28 (= 1+2+4+7+14).

Yes, you guessed it right! That’s why 6/28 i.e. 28th June is considered Perfect Number Day!
