	// do stuff
}

List factors of one or more numbers

$number = new Primes;
$number->checkIf(4)->isPrime();
print_r($number->showFactors());
// [4,2,1]

Count the factors

$number = new Primes;
$number->checkIf(4)->isPrime();
echo $number->countFactors();
// 3

List prime numbers in an interval

$primes = new Primes;
print_r($primes->giveMePrimesBetween(1,10));
// [2,3,5,7]

Return the result in json format

$number = new Primes;
$number->checkIf(4)->isPrime();
