C Exercises: Read an integer and compute all its divisors

C Basic Declarations and Expressions: Exercise-121 with Solution

Find and print all divisors of an integer

Write a C program that reads an integer and finds all the divisors of the said integer.

Sample Solution:

C Code:

#include <stdio.h>

int main () {
    int i, n;

    // Prompt user for input
    printf("Input a number (integer value):\n");

    // Read an integer value 'n' from user
    scanf("%d", &n);

    // Print a message indicating what the program will do
    printf("\nAll positive divisors of %d \n",n);

    // Loop through numbers from 1 to 'n'
    for (i = 1; i <= n; i++) {

        // Check if 'i' is a divisor of 'n'
        if (n % i == 0) {
            printf("%d\n", i); // Print 'i' if it is a divisor of 'n'
        }
    }

    return 0; // End of program
}

Sample Output:

Input a number (integer value):
35

All positive divisors of 35
1
5
7
35

C programming Code Editor:

Previous: Write a C program to print a sequence from 1 to a given (integer) number, insert a comma between these numbers, there will be no comma after the last character.
Next: Write a C program that reads two integers m, n and compute the sum of n even numbers starting from m.
