Quote of the day..
"It is not enough to do your best; you must know what to do, and then do your best."
Definition of prime 1
An integer greater than one is called a prime number if its only positive divisors (factors) are one and itself. For example, the only divisors of 11 are 1 and 11, so 11 is a prime number, while the number 51 has divisors 3, 17 and 51 itself (51 = 3•17), making 51 not a prime number.
Definition of prime 2
A positive integer that is not divisible without remainder by any integer except itself and 1, with 1 often excluded.

What is the square number of 87?
The square of a number (here 87) is the result of the product of this number (87) by itself (i.e., 87 × 87); the square of 87 is sometimes called "raising 87 to the power 2", or "87 squared".
What are the multiples of 87?
The multiples of 87 are all integers evenly divisible by 87, that is all numbers such that the remainder of the division by 87 is zero. There are infinitely many multiples of 87. The smallest multiples of 87 are:
How to determine whether an integer is a prime number?
To determine the primality of a number, several algorithms can be used. The most naive technique is to test all divisors strictly smaller to the number of which we want to determine the primality (here 87). First, we can eliminate all even numbers greater than 2 (and hence 4, 6, 8 …).
