Prime factorisation
... A prime number is a number that has exactly two factors. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, etc. Note that 1 is not classed as a prime number (as it uniquely has just 1 factor). Any whole number can be written as a product of prime numbers. We can find the prime factorisatio ...

... this property, because 32 + 42 = 52 . No right triangle, whose sides have integer lengths, can have a side of length 1 or 2. So this is the smallest such right triangle. The three numbers 3, 4, and 5, taken together, are called a Pythagorean triple. We will write this as [3; 4; 5]. Every number from ...
