What are the Factors of 104?
Factors of 104 are the numbers which when multiplied in pairs give the product as 104. These factors can be negative as well. The factor of a number is that number which divides it completely, i.e., leaves no remainder.For example: To find the factors of the number 104, we will have to perform division on 104 and find the numbers which divide 104 completely, leaving no remainders.
The diagram below provides the representation of the above definition:
How to Calculate the Factors of 104?
To calculate the factors of any number, say, 104, we need to find all the numbers that would divide 104 without leaving any remainder. We start with the number 1, then check for numbers 2, 3, 4, 5, 6, 7, etc. up to 52 (half of 104). The number 1 and the number itself are always factors of the given number.
Refer to the following table to check division 104 by its factors:
S.No.  Division  Factor 

1.  104 ÷ 1 
Remainder = 0 Hence, Factor = 1 
2.  104 ÷ 2 
Remainder = 0 Hence, Factor = 2 
3.  104 ÷ 4 
Remainder = 0 Hence, Factor = 4 
4.  104 ÷ 8 
Remainder = 0 Hence, Factor = 8 
5.  104 ÷ 13 
Remainder = 0 Hence, Factor = 13 
6.  104 ÷ 26 
Remainder = 0 Hence, Factor = 26 
7. 
104 ÷ 52 
Remainder = 0 Hence, Factor = 52 
8. 
104 ÷ 104 
Remainder = 0 Hence, Factor = 104 
Hence, the factors of 104 are 1, 2, 4, 8, 13, 26, 52 and 104.

Factors of 104 by Prime Factorization
Prime factorization of a number refers to breaking down the number into the form of products of its prime factors.
There are different methods that can be used for the prime factorization of a number.
Method 1: Division Method
To find the prime factors of 104 using the division method, follow these steps:
 Step 1. Start dividing 104 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
 Step 2. After finding the smallest prime factor of the number 104, which is 2, divide 104 by 2 to obtain the quotient (52).
104 ÷ 2 = 52
 Step 3. Repeat step 1 with the obtained quotient (52). Again, the prime factor for 52 would be 2,
52 ÷ 2 = 26
Similarly,
26 ÷ 2 = 13
13 ÷ 13 = 1
So, the prime factorization of 104 is, 104 = 2 × 2 × 2 × 13 = 2^{3} × 13
Method 2: Factor Tree Method
We can follow the same procedure using the factor tree of 104 as shown below:
So, the prime factorization of 104 is, 104 = 2 × 2 × 2 × 13 = 2^{3} × 13. Further, find the products of the multiplicands in different orders to obtain the composite factors of the number. Thus, all the factors of 104 can be written, including both the prime and composite numbers, as, 1, 2, 4, 8, 13, 26, 52, 104
Factors of 104 in Pairs
Pair factors of a number are two numbers which, when multiplied together, give that number. The pair factors of 104 would be the two numbers which, when multiplied, give 104 as the result.
The following table represents the calculation of factors of 104 in pairs:
Factor Pair  Pair Factorization 

1 and 104 
1 × 104 = 104 
2 and 52 
2 × 52 = 104 
4 and 26 
4 × 26 = 104 
8 and 13 
8 × 13 = 104 
Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 104. They are called as negative pair factors.
Hence, the negative factor pairs of 104 would be ( 1, 104 ), ( 2, 52), ( 4, 26), and ( 8, 13).
Important Notes:
 Only whole numbers and integers can be factors.
 Only composite numbers can have more than two factors.
 The smallest factor of a number is 1 and the biggest factor of a number is the number itself.
