UNIT 8: FACTORING
To
'factor'
a number means to break it up into numbers that can be multiplied together
to get the original number.
EXAMPLES:
6 = 3 X 2 <== The factors of 6 are 3 and 2
9 = 3 X 3 <== The factors of 9 are 3 and 3
Sometimes, numbers can be factored
into different combinations.
For example: 8 = 4 X 2 and 2 X 2 X 2
Two different ways to factor:
How about 18? 18 = 9 X 2 or 6 X 3
Factor the following numbers. I will factor the first one for you!
1)
10 = 5 X 2
