Web20 jan. 2024 · To find the number of divisors you must first express the number in its prime factors. 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. Web8 jun. 2024 · So the number of divisors is trivially ( e 1 + 1) ⋅ ( e 2 + 1) . A similar argument can be made if there are more then two distinct prime factors. Sum of divisors We can use the same argument of the previous section. If there is only one distinct prime divisor n = p 1 e 1 , then the sum is: 1 + p 1 + p 1 2 + ⋯ + p 1 e 1 = p 1 e 1 + 1 − 1 p 1 − 1 Web$\begingroup$ For example, 12=2^2*3 has 6 divisors. To make more divisors, we could multiply by 2,3, or 5. This will take us to 24, with 8 divisors, 36 with 9, or 60 with 12. So … pickens county government sc

Web3 jun. 2024 · Instead of checking all numbers until number / 2 , it's enough to search until sqrt (number) , and count the divisor pairs. For example, in the case of 6, initialize sum = 1, because 1 will be always part of the sum, and then when you see 2, also add 6 / 2 to the sum. (You can get sqrt with #include "math.h" .) WebJust looking at each of the exponents, we have 2,1,1. Add one to each of them to get 3,2,2 and multiply them to get 3*2*2 = 12. This means that 60 has 12 divisors (including 1 and 60 itself). Indeed, the positive divisors of 60 are, in ascending order, 1,2,3,4,5,6,10,12,15,20,30,60. top 10 netflix shows to watchWebDivisors are numbers which perfectly divides a number.
