Investigate index notation and represent whole numbers as products of powers of prime numbers

Elaborations

• defining and comparing prime and composite numbers and explaining the difference between them (Skills: Literacy, Numeracy, Critical and Creative Thinking)
• applying knowledge of factors to strategies for expressing whole numbers as products of powers of prime factors, such as repeated division by prime factors or creating factor trees (Skills: Numeracy, Critical and Creative Thinking)
• solving problems involving lowest common multiples and greatest common divisors (highest common factors) for pairs of whole numbers by comparing their prime factorisation (Skills: Numeracy, Critical and Creative Thinking)
