Lucien randomly picks two distinct numbers at the same time from the following group of numbers: 
. If the product of the 2 numbers is also a member of this group, how many selections can be done?

If i have a number, say 
with prime factorization 
, and I want to find 
numbers that multiply to , does anybody know a formula for this?

You’ve never seen an AMC 8 quite like this…
We, ChaitraliKA and Aaronjudgeisgoat, present
THE 2026 AMC 8C
Context
This is a totally legit mock test that you can use to predict what your real AMC 8 score will be!
We created many high quality problems for this test, and put our blood, sweat, and tears into it (and if u dont take it we’ll put your blood into it as well). We GUARANTEE that when you take a look at the problems, you will be stunned by the sheer quality oozing out of them. We know this for certain as we got this exact reaction from every single newborn baby that volunteered to take this test. This mock is perfect, not just for people looking to ace the AMC 8 next year, but even for high schoolers.
You have two options on how to take it: Google Docs or MathDash

Problems
Please read the guidelines carefully, and submit your answers for grading to ChaitraliKA and Aaronjudgeisgoat through AoPS PMs. We will send you the solutions as well, once we have graded you.
MathDash:

If you do it on MathDash, we will still send you your final score through AoPS PMs, due to some issues.
We expect to start grading on April 15.
The leaderboard will be updated on the MSM post.
Good luck
!
Please don't get this locked again. I will be very sad if that happens, because this is my 1000th post
. We put a lot of effort into this. If you're going to be a goody-two-shoes, just try to solve the legit problems and ignore the rest.

This was my first time making a mock, I wanted to make it as realistic as possible. As a person who has never taken an AMC 8 before, I thoroughly researched the types of problems and the format before making this. After some deep analysing, I have come to the conclusion that our mock highly resembles an AMC 8 with a -100% margin of error. I personally enjoyed making this, and put my heart and soul into making the problems and writing out the solutions. There was a lot of collaboration and every question has approval from both of us. As the most respected Cringe Nerdy Mathematician in history, I can guarantee you that it's not only about the math, it's about the experience of taking it. Please scroll down and take the test now. Thank you.

After writing a MATHCOUNTS mock, I figured I would try and take it a step further - create an AMC 8 mock. As a fellow person who has never taken an AMC 8 before, I knew there was work needed to be done before I could accurately create one. I thoroughly reviewed the rules for this test, as well as the format. I even made sure to make every single answer choice viable, simulating the silliable nature of the actual AMC 8. We reviewed every single question, answer and solution, and after cross-comparing it with actual MAA exams, I found that it's not 100% accurate to the exam, but 200% accurate. That's right, it's accurate and even more accurate. Overall, this was a very fun experience, creating my first AMC mock so that people in need of math problems have something to work on. I thank @ChaitraliKA for giving me the opportunity to problem write, and I had a very fun time collaborating with the Cringiest and Nerdiest Mathematician of them all. In conclusion, I implore you to click the link below and proceed with the test, as not only will you learn, you will have fun.
Thank you for your blood.

Hello guys,
I think we should start a factoring marathon. Post your solutions like this , and your problems like this . Please make your own problems, and I'll start off simple:

The oldest, shortest words — "yes" and "no" — are those which require the most thought.
