Lesson 18 (in part): Prime Factorization & Factor Trees
A prime number can be divided evenly only by 1 or itself. Also, it must be a
whole number greater than 1.
A factor of a number is a number that when multiplied by another value
equals that number. Example: 2 x 3 = 6 , so 2 and 3 are both factors of 6.
"Prime Factorization" is finding which prime numbers multiply together to
make the original number.
A"Factor Tree" can help with prime factorization: find any factors of the
number, then the factors of those numbers, etc, until we can't factor any
more.
