Count the number of factors for composite number other than perfect sq

1.	Count the number of factors for composite number other than perfect square is that even or odd
Answer» ONG>Step-by-step explanation: Let the number be N And it can be expressed to the product of the power of PRIMES p1, p2,...... pk N=p1^n1×p2^n2........... ×pk^nk No of DIVISORS d(N)=(n1+1)(n2+1).......(nk+1) For example:- 1125=3²×5³ Here n1=2 and n2=3 Number of divisors [d(N)]=(2+1)(3+1)=3×4=12

Count the number of factors for composite number other than perfect square is that even or odd

Answer» ONG>Step-by-step explanation:

Let the number be N

And it can be expressed to the product of the power of PRIMES p1, p2,...... pk

N=p1^n1×p2^n2........... ×pk^nk

No of DIVISORS

d(N)=(n1+1)(n2+1).......(nk+1)

For example:-

1125=3²×5³

Here n1=2 and n2=3

Number of divisors [d(N)]=(2+1)(3+1)=3×4=12
