What are Divisors of 12

A number n is called a divisor of 12 if the fraction $\dfrac{12}{n}$ is an integer. Note that if 12/n=m is an integer, then both m and n will be the divisors of 12.

To find the divisors of 12, we need to find the numbers n such that 12/n becomes an integer. We have:

12/1=12	1, 12 are divisors of 12.
12/2=6	2, 6 are divisors of 12
12/3=4	3, 4 are divisors of 12

So we conclude:

The divisors of 12 are 1, 2, 3, 4, 6, and 12.

Thus, the total number of divisors of 12 is six.

Sum, Product & Number of Divisors of 12

The prime factorization of 12 is given below.

12 = 2²×3¹

(i) By the number of divisors formula, we have that the number of divisors of 12 is

=(2+1)(1+1)=3×2=6.

(ii) By the sum of divisors formula, we have that the sum of the divisors of 12 is

$=\dfrac{2^3-1}{2-1} \times \dfrac{3^2-1}{3-1}$

$=\dfrac{8-1}{1} \times \dfrac{9-1}{2}$

$=7 \times 4=28$

(iii) By the product of divisors formula, we have that the product of the divisors of 12 is

=12^{(Number of divisors of 12)/2}

=12^6/2

=12³
