Best Answer

A factor tree is very useful when identifying the prime factors of a number. You draw two lines off of it and write two numbers that multiply together to make that number. If one of the numbers cannot be divided any further, then circle it. That is a prime number.

Draw two lines off of numbers that can be divided further, so you have multiple branches dividing off into certain numbers. Once all the numbers have been divided down, you are left with prime numbers which you can then multiply to get back to the original number.

How do you identify a number if its prime or composite number?

To identify whether a number is prime or composite, look at its factors. A prime number has exactly two factors: one and itself. A composite number has more factors and can be written as the product of prime numbers. For example: Factors of 17: 1 and 17 so 17 is prime. Factors of 102: 1, 2, 3, 6, 17, 34, 51 and 102 so 102 is composite. It can be expressed as the product of prime numbers by prime factoring: 2 x 3 x 17
