Question

For n=1451520
1) Find the total number of divisors
2) Find even number of divisors.

Answer 1

Answer:

Step-by-step explanation:

100 = 25 * 4 = 2² * 5²

We know that,

For n =

d(N)=

So here,

p1 = 2 , n1 = 2

p2 = 5 , n2 = 2 .

So,

d(100) = (2+1)(2+1) = 3 * 3 = 9 .

Number of odd divisors = (2+1) = 3 .

Therefore, Number of even divisors = 9 - 3 = 6 .

Here, d(N) means the total number of divisors of N.

Removing the power of 2 from calculating of d(N) , We get odd divisors
