TRANSCRIPT

• Prime Numbers and Prime Factorizations

• 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

• 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

• 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
