Sphenic Number
In Mathematics Sphenic number is a postive integer which is a product of three distinct prime numbers.
All sphenic numbers have exactly eight divisors. If we express the sphenic number as n=p.q.r, where p, q, and r are distinct primes, then the set of divisors of n will be: {1,p,q,r,pq,pr,qr, n}.
