Highlights of Divisors of 48

A number n is a divisor of 48 if $\dfrac{48}{n}$ is an integer. Note that if 48/n=m is an integer, then both m and n will be the divisors of 48.

To find the divisors of 48, we need to find the numbers n such that 48/n becomes an integer. We have:

No numbers other than 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48 can divide 48. So we conclude that

The divisors of 48 are:

1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.

Thus, the total number of divisors of 48 is ten. See that 24 is the biggest proper divisor of 48.

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

As the divisors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48, we can say that:

The negative divisors of 48 are -1, -2, -3, -4, -6, -8, -12, -16, -24, and –48.

The divisors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. Among these numbers, only 2 and 3 are prime numbers. So we obtain that:

The prime divisors of 48 are 2 and 3.

The prime factorization of 48 is given below.

48 = 2⁴× 3¹

(i) By the number of divisors formula, we have that the number of divisors of 48 is

=(4+1)(1+1)=5×2=10.

(ii) By the sum of divisors formula, we have that the sum of the divisors of 48 is

$=\dfrac{2^5-1}{2-1} \times \dfrac{3^2-1}{3-1}$

$=\dfrac{32-1}{1} \times \dfrac{9-1}{2}$

$=31 \times 4=124$

(iii) By the product of divisors formula, we have that the product of the divisors of 48 is

=48^{(Number of divisors of 48)/2}

=48¹⁰^/2

=48⁵
