How do you find the divisors of a number?
From the table, it’s easy to see that there are 5 x 3 = 15 divisors of 144. In general, if you have the prime factorization of the number n, then to calculate how many divisors it has, you take all the exponents in the factorization, add 1 to each, and then multiply these “exponents + 1″s together.
How do I find the divisors of a number in Python?
Finding divisors of a number with Python
- def get_divisors(n): for i in range(1, int(n / 2) + 1): if n % i == 0: yield i yield n.
- def prime_factors(n): i = 2 while i * i <= n: if n % i == 0: n /= i yield i else: i += 1 if n > 1: yield n.
How do you find the divisors of a number in Java?
To get the divisor of a number N, we should divide N by all numbers in between 1 and N including 1 and N. We will use modulus operator which gives reminder. If reminder is zero, we can say given number is divisible by another number. For ex: 10%2= 0 (10 is divisible by 2 without a reminder)
How do I get the divisors of a number in CPP?
“find divisors of a number c++” Code Answer
- // https://www.geeksforgeeks.org/count-divisors-n-on13/
- int countDivisors(int n) {
- int cnt = 0;
- for (int i = 1; i <= sqrt(n); i++) {
- if (n % i == 0) {
- // If divisors are equal,
- // count only one.
- if (n / i == i)
