52 is composite 
prime
can be divided evenly only by 1, or itself
but 52 can divided by 2,4,13, etc...
hope it helps
If it is prime, it cannot be split in 2 numbers that multiply to equal it. Look at the last number of the number to get a hint first. The last number of 52 is a 2. If you recall, any number that ends ina  2 or 0 can be divided by 2:

  52
  /  \
2  26
    /  \
   2   13 

There the number is fully factored.
