The Ministry is migrating nzmaths content to Tāhurangi.           
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

An integer a is a factor of an integer b if a divides b. It is often helpful to state the number set that we are working in. For instance, if we operate within the set of natural numbers, then the factors of 6 are 1, 2, 3, and 6 since those are the natural numbers that divide 6. Similarly, the factors of 28 are 1, 2, 4, 7, 14, and 28. (See also Common factor)
