In number theory, the fundamental theorem of arithmetic, also called the unique factorization theorem or the unique-prime-factorization theorem, states that every integergreater than 1 either is prime itself or is the product of prime numbers, and that this product is unique, up to the order of the factors. For example,
1200 = 24 × 31 × 52 = 3 × 2 × 2 × 2 × 2 × 5 × 5 = 5 × 2 × 3 × 2 × 5 × 2 × 2 = etc.
The theorem is stating two things: first, that 1200 canbe represented as a product of primes, and second, no matter how this is done, there will always be four 2s, one 3, two 5s, and no other primes in the product.
The requirement that the factors be prime is necessary: factorizations containing composite numbers may not be unique (e.g. 12 = 2 × 6 = 3 × 4).
This theorem is one of the main reasons for which 1 is not considered as a Prime number: if 1 were prime, the factorization would not be unique, as, for example, 2 = 2×1 = 2×1×1 = ...
Book VII, propositions 30 and 32 of Euclid's Elements is essentially the statement and proof of the fundamental theorem. That was written around 300 B.C.

What is the smallest number with prime factors?
There isn't one. Negative numbers have prime factors and numbers don't stop. The smallest positive numbers with a prime factor is 2.
Is 19 is prime number?
19 YES, 19 is prime because 2,3,4,5,6,7,8,9,do not go in to 19. I stop at nine because 18 is one under 19 and 9 x 2=18. The only factors of 19 are 1 and itself, making it a prime number.

What is one prime factorization of 293?
You've come to the right place. Here is the answer: None, because 293 is a prime number.
What number is a square number but not a prime number and is less than 100?
No square number is a prime number, since it has the number you squared as a factor. There are several square numbers less than 100. Just calculate the squares of all numbers, starting with 1, until you reach or pass 100. Then stop.
What is all the prime numbers?
Prime numbers never stop, it is impossible to list them all.
How can you show that a number is prime or not?
To show that it's NOT prime, you have to find that in addition to '1' and itself, the number has another factor.First, look for signs of obvious factors. The easy ones are 2, 3, 5, and 10.-- If the number ends in 2, 4, 6, or 8, it's an even number, meaning 2 is a factor. It's not prime, andyou can stop right there.-- If the sum of its digits is divisible by 3, then the whole number is divisible by 3. It's not prime, and you can stop.-- If the number ends in 5, it's divisible by 5. It's not prime, and you can stop.-- If the number ends in 0 (zero), it's divisible by 10. It's not prime, and you can stop.If none of these pans out, then you have to slog through it the slow way. One after another, divide thenumber by all the numbers from 2 up to half of the number. If any of the divisions comes out even, then thenumber is not prime, and you don't have to try any more divisions.
What is the prime factorization for the number 88?
An easy way to find the prime factorization of a number is to find the lowest prime number that is a divisor of that number, and perform a division. By repeating this process, you collect the prime factorization of your original number. For example: 88 is divisible by 2, which is the lowest prime number we can divide it by. 88/2 = 44 44 is divisble by 2 again 44 / 2 = 22 22 is STILL divisible by 2 22 / 2 = 11 and now we have the number 11, which is prime so we stop. Our prime factorization is therefore three 2's and an 11: 2, 2, 2, 11
