WebJul 19, 2024 · The answer for an odd number X is X itself. The answer for an even number X is equal to the answer for X/2. This is true because X and X/2 have the same odd divisors. ( if X = 4 then 4 and 2 both have 1 as greatest odd divisor). If we want to find answer in range [1, N], then first we need to determine the sum of all the odd numbers WebIt turns out that the "trick" can be used the way you mentioned to find the number of odd positive divisors, including 1. So to find the total number of factors, we can add one to each to power in the prime factorization of an integer, then multiply all the (power + 1)s together. For 540, we would have (2 + 1)(3 + 1)(1 + 1) = 24 factors. ...
WebEach pair has one odd number and one even number, so $2b$ has exactly as many odd divisors as even divisors. Now let's show that no number divisible by $4$ can be special. The idea is that if a number is divisible by $4$, then it has "too many" even divisors. I will not write out the details, but you should. The idea goes as follows. Take a ...
