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 = 21 × 111
(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
=224/2
=222
=484
