WebMar 21, 2024 · Steps to find the prime factors of a number. while num is divisible by 2, we will print 2 and divide the num by 2. After step 2, num must be always odd. Start a loop from I = 3 to the square root of n. If i divide num, print i, and divide num by i. After i fail to divide num, increment the i value by 2 and continue. WebHere, we have used a for..else statement to check if num is prime. It works on the logic that the else clause of the for loop runs if and only if we don't break out the for loop. That condition is met only when no factors are found, which means that the given number is prime. So, in the else clause, we print that the number is prime. Share on:
