CSES - Counting Divisors

WebIn general, it is very easy to write down the number of divisors if you know the prime factorization. Let's use a smaller example, say 60. As 60 = 2 2 ⋅ 3 ⋅ 5, we can have either 0, 1, or 2 factors of 2, either 0 or 1 factor of 3, and either 0 or 1 factor of 5. So in total, we have 3 ⋅ 2 ⋅ 2 = 12 divisors of 60.

WebJul 10, 2024 · Since each number is $\le 10^6$, it can have at most $7$ distinct prime divisors, since for the product of $8$ smallest primes: $2 \cdot 3 \cdot 5 \cdot 7 \cdot 11 \cdot 13 \cdot 17 \cdot 19 &gt; 10^6$. Therefore, each number has at most $2^7$ distinct divisors.

WebMay 28, 2024 · The approach that I took was that any number that has to divide all the numbers must be less than or equal to the smallest number in the array. For e.g., if the array is [6 90 12 18 30 18] - any divisor cannot be greater than 6, because that would not divide 6. Based on above logic, here's the code that I wrote: WebOct 13, 2024 · No. The 8 divisors include the factors 24 and 1. To see this, you can list out all the ways to multiply two numbers to get to 24, and count all the unique factors. 1 x 24 2 x 12 3 x 8 4 x 6 So, as shown above, there are 8 different divisors of 24, including 1 and 24.

WebTo know how to calculate divisors using prime factorisation, click here. We will split our number Ninto two numbers Xand Ysuch that X * Y = N. Further, Xcontains only prime factors in range and Ydeals with higher prime factors (). Thus, gcd(X, Y) = 1.
