What is the only way to create a factor tree?
Write the composite number you want to factor on a piece of paper. Write one of its factor pairs underneath it. If possible, keep breaking each factor down until all the factors are prime. All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. 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.
