A Sphenic Number is a number that is the product of exactly three distinct primes. The first few Sphenic numbers are
30, 42, 66, 70, 78, 102, 105, 110, 114. This is sequence A007304 in the OEIS.
Write a program or function to determine whether an inputted integer is a Sphenic number.
An integer between 0 and 10^9, which may or may not be a Sphenic Number.
A truthy/falsy value indicating whether the input is a Sphenic Number.
30 -> true 121 -> false 231 -> true 154 -> true 4 -> false 402 -> true 79 -> false 0 -> false 60 -> false 64 -> false 8 -> false 210 -> false
