Answer to Factors of 22

The factors of 22 are 1, 2, 11, and 22.

How to solve the problem: hints

To find the factors of 22, we can follow these steps:

1. Determine the criteria for judging whether a number is a factor. A number is a factor of 22 if it divides 22 without leaving a remainder.

2. List all the numbers starting from 1 up to the given number, which is 22 in this case.

3. Use each number as a divisor and verify whether it is a factor by dividing 22 by the number. If the division results in an integer value, then the number is a factor of 22.

4. Finally, collect all the numbers that are factors of 22.

Let's now go through a step-by-step solution to find the factors of 22.

Step-by-step solution

1. The criteria for judging whether a number is a factor of 22 is that it should divide 22 without leaving a remainder.

2. List all the numbers starting from 1 up to 22: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22.

3. Use each number as a divisor and verify whether it is a factor of 22:

   • 1 is a factor of 22 since 22 ÷ 1 = 22.
   • 2 is a factor of 22 since 22 ÷ 2 = 11.
   • 3 is not a factor of 22 since 22 ÷ 3 = 7.33 (not an integer).
   • 4 is not a factor of 22 since 22 ÷ 4 = 5.5 (not an integer).
   • 5 is not a factor of 22 since 22 ÷ 5 = 4.4 (not an integer).
   • 6 is not a factor of 22 since 22 ÷ 6 = 3.67 (not an integer).
   • 7 is a factor of 22 since 22 ÷ 7 = 3.14 (not an integer).
   • 8 is not a factor of 22 since 22 ÷ 8 = 2.75 (not an integer).
   • 9 is not a factor of 22 since 22 ÷ 9 = 2.44 (not an integer).
   • 10 is not a factor of 22 since 22 ÷ 10 = 2.2 (not an integer).
   • 11 is a factor of 22 since 22 ÷ 11 = 2.
   • 12 is not a factor of 22 since 22 ÷ 12 = 1.83 (not an integer).
   • 13 is not a factor of 22 since 22 ÷ 13 = 1.69 (not an integer).
   • 14 is not a factor of 22 since 22 ÷ 14 = 1.57 (not an integer).
   • 15 is not a factor of 22 since 22 ÷ 15 = 1.47 (not an integer).
   • 16 is not a factor of 22 since 22 ÷ 16 = 1.38 (not an integer).
   • 17 is not a factor of 22 since 22 ÷ 17 = 1.29 (not an integer).
   • 18 is not a factor of 22 since 22 ÷ 18 = 1.22 (not an integer).
   • 19 is not a factor of 22 since 22 ÷ 19 = 1.16 (not an integer).
   • 20 is not a factor of 22 since 22 ÷ 20 = 1.1 (not an integer).
   • 21 is not a factor of 22 since 22 ÷ 21 = 1.05 (not an integer).
   • 22 is a factor of 22 since 22 ÷ 22 = 1.

4. Finally, we collect all the numbers that are factors of 22: 1, 2, 11, and 22.

Pair Factors and Negative Pair Factors of Factors of 22

The pair factors of 22 are the numbers that can be multiplied together to get 22. In this case, the pair factors are (1, 22) and (2, 11).

The negative pair factors of 22 are the pair factors with one positive and one negative number. In this case, the negative pair factors are (-1, -22) and (-2, -11).

Prime Factorisation of 22

Prime factorisation is the process of expressing a number as a product of its prime factors. To find the prime factorisation of 22, we can start by dividing it by the smallest prime number, which is 2.

22 ÷ 2 = 11

Since 11 is a prime number, the prime factorisation of 22 is 2 × 11.
