A Prime number is a positive integer with two factors: one and the number itself. If you test the numbers up to the square root and your number is not divisible by any of them, it's prime.
You multiplied the given prime factorization to find the number.
No. A given number need not even be divisible by a given prime.
That's a prime factor.
The only even prime number is 2.
prime factor = prime number which can be divided into the given number with no remainder ie 2
One can tell whether a number is prime if it got only two divisors which is 1 and the number itself.
A mirror prime.
Since there are an infinite number of prime numbers, there are infinite numbers with any given number of prime factors.
No.551218171009141211314 is not a prime number.It is divisible by 2 (and 275609085504570605657, of course, but which is also not a prime number!)But ...551218171009141211267 is the prime number nearest belowthe number in the question, and551218171009141211417 is the next higher prime number.So the nearest prime number to 551218171009141211314 is 551218171009141211267, being only 47 less than the given number, whereas 551218171009141211417 is 103 more than the given number.

A number which is divisible by itself and 1 is called prime number. A prime number has only two factors.But, 836475 is also divisible by5, i.e. 836475 has more than two factors.Therefore, the given number is not prime.In order to show that given number is not prime there is no need to find all the factors, we should show that given number has more than two factors.
