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
Peterson Number:145 = 1! + 4! + 5!number=sum of (factorials of digits)
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.
Consecutive identical digits could be digits that are the same and appear next to one another in a number. For example, the hundreds and tens digits in 1442 could be considered consecutive identical.

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.
