"Web21 jul. 2015 · We find the common divisors of 24 and 36. Their common divisors are : 1,2,3,4,6,12. Do you notice that the highest common divisor of 24 and 36 is 12 and {1,2,3,4,6} are divisors of 12 as well. So our question just breaks down to finding the number of divisors of their gcd.

WebI solved a similar problem on codechef a while ago, the key idea is to use inclusion-exclusion principle. If a number X is a multiple of Y, then X is also a multiple of all of Y 's divisors. Now count for each number Y, the number of it's multiples that are present in your array and then apply inclusion-exclusion by making a loop from the highest Y to 1 … WebSo 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

Web16 okt. 2024 · Iterate from x = 2 to sqrt (N), to find all divisors of N. For any value x, check if it divides N. If it divides, then keep dividing N by x as long as it is divisible. Now, check if N > 1, then the pair of divisors (x, N) will have. gcd (x, N) == 1, since all the factors of ‘x’ has been eliminated from N. Similarly, check for all values of x.

Web4 aug. 2024 · 24 = 6 * 2 * 2 (Every divisor is square free with divisor count = 3) 24 = 3 * 2 * 2 * 2 (Every divisor is square free with divisor count = 4) Hence, appropriate answer would be 3 (24 = 6 * 2 * 2). Now if we observe carefully, we can’t group a prime factor with itself but with another prime factor. WebList of submissions of 2110030070_3 on various Competitive Programming websites.
