Factors are numbers you can multiply together to get another number.
For example, 2 and 3 are factors of 6 because 2 x 3 = 6. Some numbers

In each case, count 1 as a factor.
a.) Which have exactly 1 factor?
b.) Which have exactly 2 factors?
c.) Which have exactly 3 factors?
d.) Which have exactly 4 factors?
e.) Which have exactly 5 factors?
2.) By examining your answer to question 1, can you see any relationships or
patterns?
3.) Use any pattern you find to predict which numbers between 1 and 100
have exactly 6 factors. Then check your prediction.
