What you the prime factorization of 216?

Answer 1

repeated division by smallest prime numbers.

divide by 2 .. 108

divide by 2 again.. 54

divide by 2 again.. 27

divide by3 .. 9

divide by 3 again .. 3

so 2x2x2x3x3x3

Answer 2

First, the square root of 210 is less than 15, so the tools we will need are the prime numbers less than 15. These are: 2, 3, 5, 7, 11, and 13.

To begin, we will divide 210 by 2.

210/2 = 105, which is an integer, so write "2" and continue.

Now we try 3.

105/3 = 35, which is also an integer, so write "3" and continue.

Now we try 5.

35/5 = 7, which is also an integer, so write "5" and continue.

We know 7 is prime...

Working backwards, we have 210 = 2*3*5*7.

Note that if one of these did not divide 210, we would have to skip it and "try again" with the next known prime. If none divided 210, then 210 would be prime.

Answer 3

2 x 2 x 3 x 13 = 156

2 x 2 x 2 x 3 x 3 x 3 = 216

Answer 4

it is 23 multiplied by 33

Answer 5

216 = 2 x 2 x 2 x 3 x 3 x 3

Answer 6

2^3 x 3^3
