How to Calculate the Factors of 26?
We can calculate the factors of a number in two ways, either by division method or by prime factorization. Let's begin calculating the factors of 26 by the division method, starting with the whole number 1.
 26 ÷ 1 = 26 and remainder is 0.
 26 ÷ 2 = 13 and remainder is 0.
 26 ÷ 13 = 2 and remainder is 0.
 26 ÷ 26 = 1 and remainder is 0.
Thus we find 26 is not divisible by any other number. We have obtained factors 1, 2, 13, 26.
Factors of 26 by Prime Factorization
Prime factorization means to express a composite number as the product of its prime factors.
 To get the prime factorization of 26, we divide it by its smallest prime factor which is 2. 26 ÷ 2 = 13.
 Since 13 is a prime number, it is divisible by 13 only.

This process goes on till we get the quotient as 1. There are no further prime factors of 26.
The prime factorization of 26 = 2 × 13.
Factors of 26 in Pairs
The pair of numbers which gives 26 when multiplied is known as factor pairs of 26. The following are the factors of 26 in pairs.
Thus we have (1,26) ; (2,13) (1,26) and (2,13) as factors of 26 in pairs.
Important Notes
 26 has more than two factors and thus it is a composite number.
 26 is a nonperfect square number. Thus, it has an even number of factors. This property holds true for every nonperfect square number.
 Factors are never fractions or decimals.
Challenging Questions

Using the prime factorization method, prove that 13 is a prime number.
Factors of 26 Solved Examples

Example 1: Ms. Silvia has a class of 26 students. She wants to divide her class into groups and give them math practice. In how many ways, she can group 26 students so that:
 A group cannot have 1 or all students of the class.
 Each group has an equal number of students.
Solution:
We already learned that the factors of 26 are 1, 2, and 13
But the groups cannot have one or all students. So we ignore 1 and 26
Thus, she can only group them in 1 way with 13 students in each group. And she can make 2 groups.

Example 2: Jack needs to ship 26 spiral notepads and 39 usual notepads. He can pack only one type of notepad in each box. Also, he must pack the same number of notepads in each box. What is the number of notepads Jack can pack in each box?
Solution:
We are already familiar with the ways of finding factors.
The factors of 26 are 1, 2, and 13
The factors of 39 are 1, 3, and 13
The factors that are common to both 13 and 26 are 1 and 13
Therefore, Jack can pack either 1 or 13 notepads in a box.

Example 3: Find the product of all the prime factors of 26.
Solution:
Since, the prime factors of 26 are 2, 13. Therefore, the product of prime factors = 2 × 13 = 26.
