How do you find the number of odd divisors?
To find the total number of divisors, we will multiply the power of each prime factor by adding $ 1 $ . Then, we will find the number of odd divisors by considering only odd prime factors. To find the number of even divisors we will subtract the number of odd divisors from the total number of divisors.

How do you find the odd factor of 360?
Detailed Solution
- Given: Number = 360.
- Concept Used: x = am × bn where a, b → Odd numbers. Odd factors = (m + 1) × (n + 1)
- Calculations: Prime factors of 360 = 23 × 32 × 51 Odd factors = (1 + 2) × (1 + 1) = 6.
- ∴ The total number of odd factors of 360 is 6. Download Soln PDF. Share on Whatsapp.
What is an odd divisor of a number?
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).
How many divisors does 360 have?
24 divisors
In mathematics The divisors of 360 are 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180 and 360, making a total of 24 divisors.
How do you know if a number is odd divisors?
To find the number of odd factors (which includes 1), we can exclude any power of 2 and do the same. For 540, we have (3 + 1)(1 + 1) = 8 odd positive factors. To find the number of even factors, we can multiply the number of odd factors by the power of 2 (not the power of 2 + 1!!!).

What 3 numbers add up to 360?
2 Answers. If you are trying to find the three numbers, they are −122 , −120 , and −118 .
What is the sum of divisors of 360?
The factors of 360 are 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360. ∴ the sum of all odd proper divisors of 360 is 78.
How do you find the number of divisors of 360?
Number of Divisors of a number 1 Consider the exponents of the prime factors of 360. 2 Increment each of the exponent obtained in previous step by 1. 3 Product of the incremented exponents from step 2 gives the number of divisors of 360. i.e $(3+1)(2+1)(1+1) = 24$
What are the odd factors of 360360?
360 has five odd factors: 3, 5, 9, 15, and 45, —contained in 360: 120, 72, 40, 24 and 8 times respectively. The odd factors 9, 15 and 45 contain factors 3 and 5 multiple times. , former Retired Teacher.
How do you find the odd number of odd divisors?
Notice that a 2 doesn’t change the number of odd divisors, but in order for the number to have an odd number of divisors, all of the multiplicands must be odd, so the corresponding a values must be even. This is equivalent to saying that all number that have an odd number of odd divisors are of the form where k ≥ 0, n ≥ 1.
How do you find the perfect square of an odd number?
Every positive integer with an odd number of divisors is a perfect square. If a number has 1 divisor, then it is 1. If a number has 3 divisors, then it is p^2 for some prime p. If a number has 5 divisors, then it is p^4 for some prime p. If a number has any other odd prime number of divisors for an odd prime n, then it is p^ (n-1) for some prime p.
