To find the total number of divisors, add 1 to each of the exponents in the prime factorization and multiply those numbers. The total number of divisors is 4*2*2*3 = 48.
The odd divisors are those that do not contain any factor of 2. To find the number of odd divisors, add 1 to each of the exponents of an odd prime factor and multiply those numbers. The number of odd divisors is 2*2*3 = 12.
ANSWERS:
total number of divisors: 48
number of odd divisors: 12
number of even divisors: 48-12 = 36
