The 2-digit number must be 20, because it is the only 2-digit number whose sum of its two even digits, 2 + 0 = 2, is greater than the product of its two even digits, 2 x 0 = 0. Moreover, 20 is a product of the two consecutive integers 4 and 5.

There are 10 digits, 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9

Without using exponents or factorials, that's it.
Logic Of Strong number: Take anumber.First findout the factorials of all the digits of the number.Then sum the factorials of all the digits.If that sum is equal to the entered number then that number is said to be a strong number.
I guess the expected answer is 97210. Using factorials and exponents very much greater number can be obtained. For example, 97210 is a number with 6880 digits. And that is without using factorials.
Yes: 1 and 0 are consecutive.
Oh, dude, consecutive identical digits are just fancy words for when you have the same number back-to-back. Like when you see 22 or 777 in a row. It's not rocket science, just a fun little pattern that shows up in numbers.

A krishnamurthy number is one whose sum of the factorials of each number is equal to the number itself. Example145sum of factorial of each digits = 1+24+120 = 145 which is the number itself.
