It is hard to draw an actual tree on here. So ill do my best to explain it.
To make a factor tree you need to get the numbers on the end of the branches to be all prime numbers. Prime numbers are numbers that can not be divided by a whole number any more to get a whole number.
426/2 = 213 [2 is a Prime number]
213/3 = 71 [71 is a prime number... 71 is one of the more difficult numbers to find out if it is prime or not but believe it is prime]
Now take all ofthe numbers that you used... 426, 213, 71, 3, and 2 and use them in your factor tree.
Put 426 at the top of the tree. Make two branches with 213 and 2 coming off of these branches. From the 213 make two more branches making 3 and 71 coming off from these branches. If you do it correctly you will see the 2, 3, and 71 are at the end of the branches. All these numbers are prime numbers. Now you have you completed factor tree!

83 is prime. No tree.
61 is already prime. It doesn't need a tree.
When the bottom branch consists entirely of prime numbers.
