WebAny number which is not prime can be written as the product of prime numbers: we simply keep dividing it into more parts until all factors are prime. For example, Now 2, 3 and 7 are prime numbers and can’t be divided further. The product 2 × 2 × 3 × 7 is called the prime factorisation of 84, and 2, 3 and 7 are its prime factors. Note that ...

Let's try 2 again: 6 ÷ 2 = 3. Yes, that worked also. And 3 is a prime number, so we have the answer: 12 = 2 × 2 × 3 . As you can see, every factor is a prime number, so the answer must be right. Note: 12 = 2 × 2 × 3 can also be written using exponents as 12 = 2 2 × 3 general english pdf notes

"Web1. Of note from your linked document is that Fermat’s factorization algorithm works well if the two factors are roughly the same size, namely we can then use the difference of two squares n = x 2 − y 2 = ( x + y) ( x − y) to find the factors. Of course we cannot know this a priori. – Daniel Buck. Sep 24, 2016 at 11:52. " - Inability to factor large prime numbers
