consider the number 210
it can be written as 210 = 2 x 5 x 3 x 7
All the factors are prime, and all the prime factors occur only once.
in such a case, the total number of factors is 2 x 2 x 2 x 2. (as many 2s' as there are prime factors).
So, the answer is 16.
consider 105.
it can be written as 105 = 3 x 5 x 7
All the factors are prime, and all the prime factors occur only once.
in such a case, the total number of factors is 2 x 2 x 2 (as many 2s' as there are prime factors).
So, the answer is 8.
