the prime factorization of 120 is:?

Answer 1

120 = 2 x 60
120 = 2 x 2 x 30
120 = 2² x 2 x 15
120 = 2³ x 3 x 5

Answer 2

2 times 3 times 4 times 5

Answer 3

ever try a factor tree? it might help. or look at it like this:

what is the lowest prime number that can go into 120? 2

120 / 2 =60

the lowest prime number of 60? 2

60 / 2 = 30

lowest prime number of 30? 2

30 / 2 = 15

lowest prime number of 15? 3

15 / 3= 5

Five is prime. the answer is 2 x 2 x 2 x 3 x 5

or do "the tree"

120 = 30 x 4
30 = 15 x 2
4 = 2 x 2
15 = 3 x 5
circle all the prime numbers, and list them in numeracle order.
120= 2 x 2 x 2 x 3 x 5 OR 2 to the third power x 3 x 5

here is a good link to help and illustrate what I mean: http://www.amby.com/educate/math/2-1_fact.html

the picture in red at this link: http://www.math.ksu.edu/~dph/010_readings/Unit1Lesson1_files/Short60.gif illustrates what I was saying with the first example.

good luck! I hope this helps! the links explain it well. i had a really good factor tree done, but then I remembered that on the answers, it excludes all the exra spaces, thus completely ruining my tree =-(

Answer 4

120 ÷ 2 = 60
60 ÷ 2 = 30
30 ÷ 2 = 15
15 ÷ 3 = 5
5 ÷ 5 = 1

120 = 2 * 2 * 2 * 3 * 5

Answer 5

2^3 x 3 x 5

Answer 6

= 2, 2, 2, 3, 5

Answer: Prime factors of 120 are 2, 2 , 2, 3 & 5.

Answer 7

2*2*2*3*5 = 2^3*3*5

Answer 8

120
2 * 60
----5 * 12
--------3 * 4
-----------2 * 2

so its 2*2*2*3*5
or 2^3 * 3 * 5
