Factors, Multiples and Prime Factorization

Whole numbers can be broken apart in two useful ways. Factors are the smaller numbers that divide a whole number evenly with no remainder. Multiples are what you get when you skip-count the number forward. Every counting number greater than 1 is either a prime — built from no factors except 1 and itself — or a composite, which can always be rewritten as a product of primes.

What this lesson teaches

1List every factor of a whole number from 1 up to and including the number itself
2Classify whole numbers as prime or composite by counting their factors
3Build a factor tree and write the prime factorization using exponents
4Generate the first several multiples of a whole number by skip counting
