# Prime Factorization of 2-Digit Numbers Worksheets

With our collection of printable worksheets, prime factorization of 2-digit numbers will no longer be an insurmountable challenge. To solve these pdfs, the learners must find the prime factors for numbers up to 100. Expressing a number as a product of two or more prime numbers requires consistent practice and great skill. Start by dividing the number by the smallest possible prime number. Continue to divide by that same factor until you must move on to the next prime number. In this way, the number 45 will be written as 3 x 3 x 5. If the student can't quite forge ahead nailing the tests of divisibility as smoothly as their peers, let them use the included answer key.

Our free 2-digit prime factorization worksheets work best for grade 4 and grade 5 children.
