E - number with the given amount of divisors
WebMar 24, 2024 · The total number of divisors for a given number (variously written , , or ) can be found as follows. Write a number in terms of its prime factorization (2) For any divisor of , where (3) so (4) Now, , so there are possible values. Similarly, for , there are possible values, so the total number of divisors of is given by (5) Web1. I don't think you are correct that you need all the a i to be equal. For example, if n = 10, the maximum number of divisors is 4, and it is achieved both at 6 and at 8 ( 6 since 6 = 2 × 3, so the number of divisors is ( 1 + 1) ( 1 + 1) = 4; and 8 because 8 = 2 3, so the number of divisors is 3 + 1 = 4 ). For n = 19, the maximum is 6, which ...

Recommended: Please try your approach on {IDE} first, before moving on to the solution. Method 1: Traverse all the elements from X to Y one by one. WebNov 18, 2024 · The divisors come from letting the exponent on 2 range from 0 to p -1 and letting the exponent on 3 range from 0 to q -1. For example, the smallest number with 35 divisors is 5184 = 2 7-1 3 5-1. Note that we did not require p and q to be different. We said p ≥ q, and not p > q. And so, for example, the smallest number with 25 divisors is
