2. Watch as it's multiples disappear!
3. Keep going until all numbers left are Prime
Prime Numbers
Prime numbers can be represented only on a straight line (a 1xn or nx1 rectangle).
They have only 2 factors: 1 and the number itself.
In a row (1 x 5)
In a column (5 x 1)
The factors of 5 are 1 and 5.
Composite Numbers 🧱
A Composite number can be represented in a rectangular form with more than 1 row and 1 column.
A composite number has more than 2 factors.
The factors of 6 are 1, 6, 2 and 3.
2 rows by 3 columns (2 x 3)
3 rows by 2 columns (3 x 2)
The Special Number: 1️⃣
The number 1 is a special number. It can only be represented in 1 way.
1 x 1
It can't be Prime, it needs two different factors: 1 and itself, but 1 only has one unique factor.
It can't be Composite it needs more than two factors.
Therefore, 1 is neither Prime nor Composite!
