Question

Two composite numbers with one factor tree

Answer 1

By definition, a prime number is only evenly divisible by itself, or the number 1, and it is greater than 1. If a number is composite, you can divide it evenly by numbers other than 1. For example, if you divide 7 by any integer other than 1, you end up with a fraction or decimal; therefore, 7 is prime. However, 8 is divisible by 2 and 4 (8/2 = 4, 8/4 = 2). Breaking down a number into its prime and composite factors is helpful for a number of mathematical processes.
Hope that works out! :D

Answer 2

I can't make a tree very easily but I will still answer you question

a composite number, if you did not already know, is a number that can be divided by a diffarent whole number and still get a whole number (exg. 4/2=2=composite 5/2=a decimal=prime)

so one composit number is 16
the factored out tree is 2*8
2*4
2*2

another is 24
the factor tree is 2*12
2*6
2*3
hope you can see the tree as I typed it out
