WebStart by dividing the given number by the smallest prime which is 2. The factors of the number above are broken down into “branches” as indicated by the line segments. After the repeated division of 2, we also arrive at the final factor of … WebDivisors of an integer in Python. We will first take user input (say N) of the number we want to find divisors. Then we will run a loop from 1 to (N+1). We do so because if we run the loop from 0 (zero) then we will get ‘Division By Zero Error’. And if we run it only N times then we will not get the number (N) as its own divisor.

WebJan 20, 2024 · Example: How many divisors are there of the number 12? 12 = 2^2 x 3 The number 2 can be chosen 0 times, 1 time, 2 times = 3 ways. The number 3 can be chosen 0 times, 1 time = 2 ways. Putting these results together we have 3 x 2 = 6 ways of finding factors of 12. This is the same example we saw before. WebIf n is perfectly divisible by i then, i will be the factor of n. In each iteration, the value of i is updated (increased by 1). This process goes until test condition i <= n becomes false,i.e., this program checks whether number entered by user n is perfectly divisible by all numbers from 1 to n and all displays factors of that number.
