What are Divisors of 64

Note that if $\dfrac{64}{n}=m$ is an integer, then by definition of divisors we can say that both m and n will be the divisors of 64.

To find the divisors of 64, we need to find the numbers n such that 64/n becomes an integer. We have:

64/1=64	1, 64 are divisors of 64.
64/2=32	2, 32 are divisors of 64
64/4=16	4, 16 are divisors of 64
64/8=8	8 is a divisor of 64

No numbers other than 1, 2, 4, 8, 16, 32, and 64 can divide 64. So we conclude that

The divisors of 64 are: 1, 2, 4, 8, 16, 32, and 64.

Find the number of divisors of 64: Thus, the total number of divisors of 64 is seven.

Sum, Product & Number of Divisors of 64:

The prime factorization of 64 is given below.

64 = 2⁶ 

(i) By the number of divisors formula, we have that the number of divisors of 64 is equal to (6+1) = 7.

(ii) By the sum of divisors formula, we have that the sum of the divisors of 64 is

$=\dfrac{2^7-1}{2-1}$

$=\dfrac{128-1}{1}$

= 127.

Therefore, the sum of the divisors of 64 is equal to 127.

(iii) By the product of divisors formula, we have that the product of the divisors of 64 is

= 64^{(Number of divisors of 64)/2}

= 64^7/2

= 8⁷ = 2097152.

So the product of divisors of 64 is equal to 2097152.
