Emily -The factors of any integer will always be a combination of prime numbers. For example, say you want the factors of 90. Start dividing by 2, then 3, then 5, etc.90 → 2 * 45 → 2 * 3 * 15 → 2 * 3 * 3 * 5So, the prime factors of 90 are 2,3,3,5 and any combination of these primes will also be a factor!Not sure if that helps
