How are the factor tree and factor ladder different?

The factor tree uses any factors for the branches, while the factor ladder factors out only prime numbers to the side of the ladder.

exponent

The small number in the air that tells how many times to write the base number then multiply them. For example, if the base is 2 and the exponent is 5, multiply: 2x2x2x2x2 which equals 32.

composite number

a number that has more than two factors

prime number

a number that only has two factors, one and itself

factor tree

a strategy using numbers and branches to find the prime factorization of whole numbers

factor ladder

a strategy using steps and prime factors to write the prime factorization of a given whole number

prime factorization

number written as the product of its prime factors ex. 24= 2x2x2x3 It is most often written in exponential form.
