34) If N=8p, where p is a prime number greater than 5, how many different positive even divisors does n have including N?
Read Solution (Total 2)
-
- 6
N,8,4,2,2p,4p
N/N =1
N/8 = 8p/8 = p
N/4 = 8p/4 =2p
N/2 = 8p/2 =4p
N/2p = 8p/2p = 4
N/4p = 8p/4p = 2
p is also a divisor but it is not even as 'p' is a prime number greater than 5 - 10 years agoHelpfull: Yes(1) No(0)
- N= 8*p=2^3*p^1
total divisors= (3+1)*(1+1)=8 - 10 years agoHelpfull: Yes(0) No(0)
