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.DivisionFactor
1.22 ÷ 1

Remainder = 0Factor = 1

2.22 ÷ 2

Remainder = 0Factor = 2

3.22 ÷ 11

Remainder = 0Factor = 11

4.22 ÷ 22

Remainder = 0Factor = 22

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 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 112 × 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).


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).
