According to the Math Warehouse, the prime factorization of 150 is 2 x 3 x 5 x 5. Several factors are identified because 150 is not a prime number.
AAA Math states that a prime number is a whole number that has only itself and one as factors. For example, seven is a prime number because its only factors are 1 and 7. Prime numbers are not always small; for example, 71 is a prime number. In contrast, a composite number has at least one other factor other than itself and one. Eight is a composite number, because 8, 1, 2, and 4 are all factors. Like prime numbers, composites numbers range from small to large.
