Prime Composite Squares Factors 15 is not a prime number because the factors of 15 are 1, 3, 5 and 15 (\(1 \times 15 = 15, 3 \times 5 = 15\)). 15 has more than 2 factors, so it is not a prime. 1 is not a prime number as it only.

Square numbers. square numbers are numbers which can form perfect squares without having any left over pieces. they are usually formed when the same number is multiplied by itself. for example, 1 x 1 = 1, 2 x 2 = 4, 3 x 3 = 9 and 4 x 4 = 16. these are all square numbers. There are three piximaths lessons on types of number: odd and even numbers looks at what it means for number to be odd or even with clear visual explanations. a differentiated main task is followed by an investigation looking at calculating with odd and even numbers. factors, multiples and primes features a step by step tutorial to determine. Identify and describe properties of prime, composite, square and triangular numbers (acmna122) * understanding that some numbers have special properties and that these properties can be used to solve problems * representing composite numbers as a product of their prime factors and using this form to simplify calculations by cancelling common.

Teaching point 3: prime numbers are positive integers that have exactly two factors. teaching point 4: a common factor is a factor that is shared by two or more numbers. a prime factor is a factor that is also a prime number. teaching point 5: a multiple of a number is the product of that number and an integer; a common multiple is a multiple. The tests for divisibility by powers of 2 and 5 arise from the fact that 10 = 2 × 5. because 10 is a multiple of 2, every multiple of 10 is a multiple of 2. thus to test whether a number is divisible by 2, we only need to look at the last digit. a number is divisible by 2 if its last digit is 0, 2, 4, 6 or 8.
