The first interactive sheet shows a table of pairs of integers for students to reveal the factors and sets of multiples. The HCF and LCM can be revealed. New pairs of digits can be shown, either easy or more challenging. Each number is shown as the product of its prime factors.

The next two sheets show sets of pairs of numbers, for students to explore the relationship between the product, HCF and LCM. The final interactive sheet similarly shows the relationship between the product, HCF and LCM for algebraic products.

There are a further five sheets of questions which may be duplicated for classroom use. These include finding the common denominator of algebraic fractions.
