A divisor for a number is such a number that when on dividing the number given 0 as remainder. A primenumber is a natural number which has exactly 2 divisors i.e 1 and the number itself. Some examples of the primenumbers are 2, 3, 5, 7 etc. whereas two numbers are said to be coprime with each other when they don't haveany common factors other than 1. The number of coprimes for a number X is the count of the numbers whichare less than the given number and is coprime with X. For example, the number of coprimes for 5 is 4.If P is the smallest number such that each of its divisors are at least 15 numbers a part and P has exactly 3divisors.
