Therefore, if a number is divisible by 9, then, recursively, all the digit sums are also divisible by 9. In this example, you will learn to check whether an integer entered by the user is a prime number or not. Naive Approach: The idea is to first count number digits (or find order). Since input number may be very large, we cannot use n % 3 to check if a number is divisible by 3 or not, especially in languages like C/C++. If the number is perfectly divisible by 2, test expression number%2 == 0 evaluates to 1 (true). The idea is based on following fact. As shown below: 1*1*1*1 + 6*6*6*6 + 3*3*3*3 + 4*4*4*4 = 1634. Given an integer N, the task is to check whether the number is divisible by the sum of its digits or not. 89 is a prime number because it is only divisible by 1 and itself. While trial division is slower than more sophisticated methods for large numbers, it is still quite efficient for small numbers. To create this article, 62 people, some anonymous, worked to edit and improve it over time. C Example. Since input number may be very large, we cannot use n % 11 to check if a number is divisible by 11 or not, especially in languages like C/C++. This Python program checks the factors using the for loop and conditional statement and prints the desired output. A check digit is a form of redundancy check used for error detection on identification numbers, such as bank account numbers, which are used in an application where they will at least sometimes be input manually.
