This grade 4 factors multiples worksheet gives 22 problems on factors, multiples, primes and composites, ordered from easy to hard, with a separate answer key.
These 22 problems practice factors, multiples, factor pairs, and prime and composite numbers from standard 4.OA.B.4. They begin with skip counting and rectangles, then move to factor pairs up to 100 and to deciding whether a number is prime.
The last six problems are word problems about chairs, cookies, savings, and stickers. Show your list of factors and check each one by multiplying.
