Find 2 factors of the number; Look at the 2 factors and determine if at least one of them is not prime; If it is not a prime factor it; Repeat this process until all factors are prime. See how to factor the number 72: 72 / \ 2 36 / \ 2 18 / \ 2 9 / \ 3 3 72 is...
The prime factorization of 888 = 23•3•37. The prime factors of 888 are 2, 3, and 37. Factor tree or prime decomposition for 888 As 888 is a composite number, we can draw its factor tree: Website Map Here is the answer to questions like: Find the prime factorization of 888 ...
2.1. Prime Factors In Section 1 we saw how a problem of number theory can reduce to a question of decomposition into prime factors in some order of an algebraic number field. We shall see other such examples later. We now consider the general problem of decomposition into prime factors. In...
The ends of all the branches are the prime factors of the original number. How do we know which prime numbers to use when dividing the original number? This will take some trial and error, hence the name Trial Division Method. A good strategy is to determine if the number is even or ...

A prime number is a whole number greater than 1 that only has whole number factors of 1 and itself. When we say that it only has whole number factors of 1 and itself, we mean the only two whole numbers you can multiply to get that number are 1 and the number itself. Twin...
This startnumber 14 has two factors 2 and 7. Now paste these two factors together (from smallest to greatest) and you'll end up with the new number 27. Repeat the procedure with number 27.27 = 3 x 3 x 3. Concatenation of these three factors gives the number 333. So step 3 ...
We find several new PWN with two square odd prime factors, and one with three square odd prime factors (see Table 6). These are the first examples of this kind. In the following, we describe the methods used in the paper. In Section 2 we start with a careful analysis of the set A...
