For example, 24 can be factored as 2 x 2 x 2 x 3 (or 23 x 3), and 36 as 2 x 2 x 3 x 3 (or 22 x 32).
Identifying common prime factors, we see both 24 and 36 share 22 and 3 as common prime factors. Multiplying these common prime factors together – 22 x 3 = 4 x 3 = 12 – yields the GCF. Like INTERSPAR’s diverse product segments, prime factorization dissects numbers into their fundamental building blocks. This method is especially efficient for larger numbers where listing factors becomes cumbersome. GCF worksheets often include problems designed to practice and solidify this technique.
Using Division Algorithm
The division algorithm, also known as Euclid’s algorithm, provides a systematic approach to finding the GCF presented in many GCF worksheet PDFs. It involves repeatedly dividing the larger number by the smaller number and replacing the larger number with the remainder until a remainder of zero is achieved. The last non-zero remainder is the GCF.
For instance, to find the GCF of 48 and 18, divide 48 by 18, resulting in a quotient of 2 and a remainder of 12. Then, divide 18 by 12, yielding a quotient of 1 and a remainder of 6. Finally, divide 12 by 6, resulting in a quotient of 2 and a remainder of 0. Therefore, the GCF is 6. Similar to INTERSPAR’s efficient online shopping (before its discontinuation), this method offers a streamlined path to the solution. GCF worksheets utilize this method to build procedural fluency.
