Prime Numbers Math Worksheets
July 18th, 2008
What are the Prime numbers between 0 and 10?
The numbers to consider are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.
Recall the definition of Prime numbers:
Definition of Prime numbers. What are Prime numbers?Prime numbers are counting numbers that can be divided evenly by only two numbers which is one and itself. A prime number has exactly two factors, 1 and itself (prime factor). |
- 0 has only one factor = 0 so 0 is not a prime number.
3 has 2 factors = 1 and 3.
-
Note that 2 is not a factor of 3 because 3 divided by 2 does not give a whole number. 3 divided by 2 is 1.5. So, 2 is not a factor of 3.
