Using Factor Tree in Math

Use Factor Tree in Math  

Factor tree has many functions in mathematics. Besides for find factor the number, factor tree can use for find gcd or lcm in math. And in this discussion maticschool want to discuss how to use the factor tree in math.

Before we use factor tree we must know about primes number. Why ? Because of primes is what will we use for factor tree. To use a factor tree we know of at least between 1-20.

prime numbers between 1-20 = 2, 3, 5, 7, 11, 13, 17, 19

Aftere we know prime numbers between 1-20. Maticschool will give an example with numbers 42.

So from factor tree above the factor of 42 is 2, 3, and 7

Note :
 - In the left position like 2 and 7 is divisor
- Divisor must prime numbers
- In the right position like 21 and 3 is results number
- Factor tree finish if the result number is prime number like in the example is 3
