A prime fatorization tree is a visual representation of a number that is broken down into only prime factors. Prime numbers are numbers that only have two factors, one and itself. For example, 5 is a prime number because the only factors of 5 are 1 and 5. In the case of 30, we can first use the factors '3' and '10'. Then breaking '10' down into factors of '5' and '2' gives you an overall answer of 3 x 5 x 2.
