    CLICK HERE TO ADVANCE TO THE NEXT PAGEMs. Bobbi Casper

  • A Prime number is a whole number that has exactly two factors, 1 and the number itself. Examples: 11, 13, 23

    PRACTICE QUESTION

    Determine whether each number is Prime.293947

    Now click here to go to the Find the Prime Factors of a Number web site. Double check your answers to make sure they are correct. When you are finished return to this page to advance to the next page.

  • A composite number is a number greater than 1 with more than two factors. Examples: 6, 10, 18

    QUESTIONDetermine if each number is prime or composite.271949

    Next click here to go to E-lab, Prime and Composite Numbers. Scroll down the page to the blue box. Click on Find Factors to check your answers above. When you are finished return to this page to advance to the next page.

  • Neither prime nor composite numbers are:

    1 - because it has only one factor, and 0 - because 0 has an infinite number of factors. CLICK HERE
