## What are Divisors of 22

A number n is a divisor of 22 if $\dfrac{22}{n}$ is an integer. Note that if 22/n=m is an integer, then both m and n will be the divisors of 22.

To find the divisors of 22, we need to find the numbers n such that 22/n becomes an integer. We have:

22/1=22 | 1, 22 are divisors of 22. |

22/2=11 | 2, 11 are divisors of 22 |

No numbers other than 1, 2, 11, and 22 can divide 22. So we conclude that

The divisors of 22 are: 1, 2, 11, and 22. |

Thus, the total number of divisors of 22 is four.

## Negative Divisors of 22

We know that if m is a divisor of a number, then -m is also a divisor of that number.

As the divisors of 22 are 1, 2, 11, and 22, we can say that:

The negative divisors of 22 are -1, -2, -11, and –22.

## Prime Divisors of 22

The divisors of 22 are 1, 2, 11, and 22. Among these numbers, only 2 and 11 are prime numbers. So we obtain that:

The prime divisors of 22 are 2 and 11.

## Sum, Product & Number of Divisors of 22

The prime factorization of 22 is given below.

22 = 2^{1} × 11^{1}

(i) By the number of divisors formula, we have that the number of divisors of 22 is

=(1+1)(1+1)=2×2=4.

(ii) By the sum of divisors formula, we have that the sum of the divisors of 22 is

$=\dfrac{2^2-1}{2-1} \times \dfrac{11^2-1}{11-1}$

$=\dfrac{4-1}{1} \times \dfrac{121-1}{10}$

$=3 \times 12=36$

(iii) By the product of divisors formula, we have that the product of the divisors of 22 is

=22^{(Number of divisors of 22)/2}

=22^{4/2}

=22^{2}

=484
