construct a factor tree for the given number. Then write out the prime factorization of the number 392, 190, 39 & 52

I can't show the tree here, but I can give you the prime factorization for one of the numbers as an example.

52 = 26 * 2 = 13 * 2 * 2

For the factor tree from 52, draw branches to 26 and 2. From 26, draw branches to 13 and 2.

Do the same method for the other numbers.

I hope this helps. Thanks for asking.
