Two different problems: A factor tree is a way to notate the process of finding the prime factorization of a given number. Once you have the prime factorizations of at least two numbers, you can combine them and find the LCM.
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.
2 x 3 x 5 x 7 = 210
That's the prime factorization of 210.
Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the highest amount of each factor.
2 x 3 x 5 x 7 = 210, the LCM

How do you identify the gcf and LCM of a pair of numbers if one number is a factor of the other number?
The GCF is the factor, the LCM is the other one.
What is the factor of 3 using factor tree method for middle school?
3 is a prime number. Prime numbers don't have factor trees. The factors of 3 are 1 and 3.
