How Prime Factor is different
We believe students learn best when they're challenged, encouraged to ask questions, and surrounded by peers who share their curiosity. Our classes build confidence, creativity, and lasting problem-solving skills.
Students don't just solve problems — they explore, discuss, and understand.
From logical reasoning to AI and linguistics, students discover ideas beyond the school curriculum.
Every student is seen, supported, and challenged at the right level.
We bring abstract concepts to life with visual models, puzzles, games, and hands-on activities.
Learn from mathematicians, engineers, researchers, and experienced educators.
Our mathematics books have been published by the American Mathematical Society.
Testimonials
"I was a student at Prime Factor Math Circle for at least five years... The math classes helped me a ton in competitions because they focus on logic and proofs, not standard school math."
"The goal of math enrichment programs such as Prime Factor is to introduce students to mathematical ideas they may never see in school, even at the university level. My son has participated in Prime Factor for the past two years. Each week I look at his homework and think, 'I wish I could have solved problems like this when I was a child.'"
"I am currently pursuing a bachelor's degree at the University of Washington after attending Prime Factor's math and computer science programs from elementary through high school. One reason I stayed for so long was their unique approach. In math classes, the emphasis was on creativity and logical reasoning. I learned techniques never offered in school. Prime Factor gave me a distinctive set of skills I couldn't have accessed elsewhere."
"At Prime Factor, students engage with challenging topics such as combinatorics, number theory, graph theory, and mathematical induction. While not part of the standard school curriculum, these ideas are important in many science and technology careers. Prime Factor focuses on building logical thinking, creative problem-solving, and the analytical thinking that technical fields value."
We'll help you choose the right level - through a short placement test or personal guidance.
