How to Calculate the Sum of All Odd Divisors of 180
Key Insights
The sum of odd divisors of 180 isn’t guessed—it’s computed with a clear, logical method. First, factor 180 into its prime components:
180 = 2² × 3² × 5¹
Odd divisors come only from the odd prime factors—excluding the factor of 2. So we focus on 3² × 5¹.
To find the sum of all divisors from this reduced set, use the formula:
For prime factor ( p^a ), sum of divisors is ((p^{a+1} - 1)/(p - 1))
Apply this to 3²:
(3³ – 1)/(3 – 1) = (27 – 1)/2 = 26/2 = 13
For 5¹:
(5² – 1)/(5 – 1) = (25 – 1)/4 = 24/4 = 6
Now multiply these sums:
13 × 6 = 78
