In other words, if we take the digits of a number and calculate the factorial of each digit, then sum those factorials, and the result is the same as the original number, then that number is called a strong number. For example, 145 is such a number because 1! + 4! + 5! = 1 + 24 + 120 = 145.
Oct 16, 2022 · Given a number N, print all the Strong Numbers less than or equal to N. Strong number is a special number whose sum of the factorial of digits is equal to the original number. For Example: 145 is strong number. Since, 1! + 4! + 5! = 145. Examples: Input: N = 100 Output: 1 2 Explanation: Only 1 and 2 are the strong numbers from 1 to 100 because ...
Dec 18, 2023 · Strong Numbers are the numbers whose sum of factorial of digits is equal to the original number. Given a number, check if it is a Strong Number or not. Examples: Input : n = 145. Output : Yes. Sum of digit factorials = 1! + 4! + 5! = 1 + 24 + 120. = 145.
Mar 14, 2023 · Strong Numbers. “In Mathematics, Strong Numbers are defined as the number whose sum of the factorial of digits is equal to the number itself.” The following examples will help you in a clear understanding of the above statement. Example 1 of Strong Numbers. Let us consider a number, 145. Here, n = 145.
Mar 27, 2024 · Strong numbers are special and unique in that they are the only ones for which the sum of each digit's factorials matches the actual number. We will discuss examples in the below section to understand strong numbers more clearly. Examples of Strong Number Example 1. Input: 145 . Output: 145 is a Strong number . Explanation: 1!+4!+5! =1+24+120 =145
Sep 11, 2023 · A number n is said to be Powerful Number if for every prime factor p of it, p 2 also divides it. For example:- 36 is a powerful number. It is divisible by both 3 and square of 3 i.e, 9. The first few Powerful Numbers are: 1, 4, 8, 9, 16, 25, 27, 32, 36, 49, 64 ….
Jun 20, 2015 · What is a Strong number? Strong number is a special number whose sum of factorial of digits is equal to the original number. For example: 145 is strong number.

Dec 28, 2023 · A strong number (also known as a digital factorial) is a number such that the sum of its individual digits, each raised to the power of itself, is equal to the number itself. For example, 145 is a strong number because 1! + 4! + 5! = 1 + 24 + 120 = 145.
Mar 7, 2024 · Leverage Python’s functional programming features like map() and sum() with lambda functions to create an ultra-compact one-liner that checks for a strong number. Here’s an example: is_strong_number = lambda num: num == sum((1, 1, 2, 6, 24, 120, 720, 5040, 40320, 362880)[int(digit)] for digit in str(num)) print(is_strong_number(145)) Output ...
May 27, 2023 · What is a Strong Number in Java?
