Darius created a factor tree and wrote the prime
factorization of 60 shown here.
What is Darius's error?
O Darius should have started the factor tree with 2 *
30.
60

O Darius did not complete the factorization: 5 is a
composite number
O Darius should have expressed 15 as 5 * 5. not 3*

O Darius should have expressed 60 as 22 x 3 x 5. not
2 x 3 x 5.
2
60 = 2 * 3x5
