What are the Factors of 22?
The factor of a number is that number which divides it completely i.e., leaving no remainder. For example: For determing the factors of the number 22, we will have to perform division on 22 and find the numbers which divide 22 completely, leaving no remainders. The below diagram provides the representation of the above definition:
How to Calculate the Factors of 22?
To calculate the factors of any number, here in this case 22, we need to find all the numbers that would divide 22 without leaving any remainder. We start with the number 1, then check for numbers 2, 3, 4, 5, etc. up to 11 (half of 22) respectively. The number 1 and the number itself would always be a factor of the given number.
Refer to the following table to check division 22 by its factors:
S.No.  Division  Factor 

1.  22 ÷ 1 
Remainder = 0 
2.  22 ÷ 2 
Remainder = 0 
3.  22 ÷ 11 
Remainder = 0 
4.  22 ÷ 22 
Remainder = 0 
Factors of 22 By Prime Factorization
Prime Factorization of a number refers to breaking down a number into the form of products of its prime factors. There are different methods that can be used to find the prime factorization of a number and hence its prime factors.
Method 1: Division Method
To find prime factors of 22 using the division method,
 Step 1. Start dividing 22 from the smallest prime number i.e., 2, 3, 5, and so on. and find the smallest prime factor of the number.
 Step 2. After finding the smallest prime factor of the number 22 i.e., 2, divide 22 by 2 to obtain the quotient (11)
22 ÷ 2 = 11
 Step 3. Repeat step 1 with the obtained quotient (11). Again, the prime factor for 11 will be 11 ( since 11 is a prime number).
11 ÷ 11 = 1
So, the prime factorization of 121 is 22 = 2 × 11
Method 2: Factor Tree Method
We can do the same procedure using the factor tree for 22 as shown in the diagram given below:
So, the Prime factorization of 22 is 22 = 2 × 11
Further, find the products of the multiplicands in different orders to obtain the composite factors of the number.
Thus, the total factors can be written including both the prime and composite numbers together.
Hence, the factors of 22 are 1, 2, 11, and 22.

Factors of 22 in Pairs
Pair Factors are the factors of a number given in pairs, when multiplied together give that original number. The pair factors of 22 would be the two numbers when multiplied together, result in the value 22.
The following table represents the calculation of pair factors of 22:
S.No.  Factor Pair  Pair Factorization 

1.  1 and 22 
1 × 22 = 22 
2. 
2 and 11  2 × 11 = 22 
Negative Pair Factors
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 22.
The negative factor pairs of 22 would be (1, 22 ) and (2, 11).
Important Notes:
 The number 22 has 4 factors, which makes it a composite number.
 The largest prime factor for 22 is 11.
 The negative factor pairs of 22 are (1, 22) and ( 2, 11).

Factors of 22 Solved Examples

Example 1: Ron is calculating the sum of all the factors of 22. Can you help him solve this?
Solution:
We know, the factors of 22 = 1, 2, 11, 22
The sum of all the factors is 1 + 2 + 11 + 22 = 36
Hence, Sum = 36 
Example 2: The common factor is the number that mutually divides two numbers. Can you find the common factors of 22 and 48?
Solution:
We know, the factors of 22 are 1, 2, 11, 22
Also, factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Thus, the common factors of 22 and 48 = 1 and 2. 
Example 3: Find the Least Common Multiple and Highest Common Factor (HCF) of 22 and 20.
Solution:
The factors of 22 are 1, 2, 11, 22 and factors of 20 are 1, 2, 4, 5, 10, 20.
Therefore, the Least Common Multiple of 22 and 20 is 220 and Highest Common Factor (HCF) of 22 and 20 is 2.
