WebThe eight divisors counted by this formula are 1, 2, 4, 8, 3, 6, 12, and 24. We also note s(n) = σ(n) − n. Here s(n) denotes the sum of the proper divisors of n, i.e. the divisors of n excluding n itself. This function is the one used to recognize perfect numbers which are the n for which s(n) = n. If s(n) > n then WebDivisors Calculator. Enter number.

WebThen add all the number of divisor to get the total number of divisors. For example for N=3, answer is 1+2+2=5. 1 for 1, 2 for 2, 2 for 3. These are number of divisor from 1 to 3. So total is 5. And also I can't compute 10^9 within 1 sec. So it has to something efficient. – PEIN Sep 6, 2011 at 17:33 WebThere is a very simple trick for this,first compute the prime factorization of $720$,which is $2^4 \times 3^2 \times 5$,the total number of factors here is $3 \times 2 \times 5 = 30$, and number of odd factors (number of factors of the odd primes)$=3 \times 2 = 6$,subtracting gives number of even factors = $24$.This method works for any number. atmanirbhar bharat date
