# Euclid's Algorithm - AQA GCSE Maths watch

1. Would I be permitted to use Euclid's algorithm for finding the highest common factor in an exam question? I am sure Edexcel allow marks for this approach, but I don't know if AQA does.
2. If you get the right answer, then sure! For GCSE it’s not really about the working if you do get the correct answer

Whilst I praise your innovation, I don't think GCSE questions are really that deep

I mean if it works it works

Ah, thanks! My teacher really emphasises on method marks, and when I look at mark schemes, I find that there are certain approaches to a question where marks are not awarded.

I know, but I find this method (in some cases) quicker and easier. Just want to be aware of my options.

I'm not sure how it would be quicker with the stuff you'll encounter at GCSE But fair play I guess.

Hahah, yeah I guess so, but there are some methods where you aren't awarded marks, and I'd rather not lose out on a few easy marks by using a different approach.

Okay, I lied. sometimes I'm a bit lazy with drawing venn diagrams and bunch of branches. Also, I've never gone wrong with euclid, and it makes checking my work at the end easier.
