In factoring out the greatest common factor, we must first find the greatest common factor. So what we’re going to do is we’re going to write down each term of this expression. So we have 12x cubed; ...

The highest common factor (HCF) is found by identifying all common factors of two numbers and selecting the largest one. For example, 8 and 12 have common factors of 1, 2 and 4. The highest common ...

To factorise an expression, we need to take out any factors that are common to each term. The process is the opposite of expanding brackets. We need to find the HCF of \(\text{10x}\) and \(\text{25}\) ...
