Find the prime factorization of each number. If the number is prime, state this. 39, 30, 27, 150, 40, 31, 210, 33. If you can, explain the steps you did to at least of the above numbers. Thanks in advance :)

For example, how would i find the prime factorization of 115?
anonymous
  • anonymous
do u know what r the prime nos?
anonymous
  • anonymous
can u list them?
anonymous
  • anonymous
2, 3, 5, 7, 11, 13, 17, 19, 23 & so on..
anonymous
  • anonymous
right :)
anonymous
  • anonymous
Okay, but i dont understand what im suppose to do with them lol
anonymous
  • anonymous
now for 115 u have to see by which prime no is 115 divisible?
anonymous
  • anonymous
it ends at 5,so divisible by 5
anonymous
  • anonymous
so do i start with 2 & go up?
anonymous
  • anonymous
yeah, but 115 isnt divisible by 2
anonymous
  • anonymous
115/5=23...ok?
anonymous
  • anonymous
ok
anonymous
  • anonymous
23 is prime
anonymous
  • anonymous
now see 23 is prime, so we r end up 115=5*23
anonymous
  • anonymous
Oh, okay.. i get it now.
