Problem solving with factors, multiples, squares and cubes

This unit on factors, multiples, squares and cubes helps pupils build on their understanding that any positive integer can be expressed as a product of its factors. This skill is used in the next unit to explore multiplying and dividing with decimals.

In this unit, pupils learnt how to identify common factors and common multiples. in this unit, pupils build on this understanding to find the LCM and HCF

In this unit pupils develop their understanding of factors and multiples, then extend this knowledge to learn general divisibility tests for integers and develop strategies to determine the highest common factor and lowest common multiple of two or more integers.

Properties of number: factors, multiples, squares and cubes

A common multiple is a number that is a multiple of two or more numbers.

Divisibility is a number’s ability to be exactly divided by another number, leaving no remainder.

A perfect square is the same as a square number.

A perfect cube is the same as a cube number.

The base is the number or term that has been multiplied by itself.

An integer exponent identifies how many times the base number has been multiplied by itself.

Evaluate means to find the value of a numerical or an algebraic expression.

A prime number is an integer greater than one with exactly two factors.

A composite number is an integer with more than two factors. All integers greater than 1 are either composite or prime

Prime factors are the factors of a number that are, themselves, prime.

Each composite number has a unique product of its prime factors.  i.e. there is only one unique way it can be written.

A composite number is an integer with more than two factors.

Prime factors are factors of a number that are, themselves, prime.

An exponent is a number positioned above and to the right of a base value. It indicates repeated multiplication.
