To find a prime factorization, divide a composite number and its factors by prime numbers until all the factors are prime. Many people find factor trees helpful in visualizing this process. Example: 210
210 Divide by two.
105,2 Divide by three.
35,3,2 Divide by five.
7,5,3,2 Stop. All the factors are prime.
2 x 3 x 5 x 7 is the prime factorization of 210.
You do a factor rainbow to find a prime factorization. You compare prime factorizations to find a greatest common factor.
3 could be a prime factor but it depends on which number you're trying to find the prime factors of.
Whatever you use, 59 is a prime number. Its only prime factor is itself.
You divide by one prime after another until you find a factor. Then you repeat the process with the quotient, starting with that factor.You divide by one prime after another until you find a factor.

Suppose you have a number N and you want to find its largest prime factor. It is probably easiest to start at the bottom.Find the smallest prime factor, p.Find its factor pair = N/p.If the second number (= N/p) is a prime, then it is the largest prime factor.if not, replace N by N/p and go back to the top.
