2, 3, 7

12 6,2 3,2,2 42 21,2 7,3,2 2 x 3 = 6, the GCF

28 is not a factor of 42.

42=2x21 21=3x7 PF=2x3x7 The PF (Prime Factorization) of 42 is 2x3x7.(Sorry, I couldn't do a factor tree, there are always helpful to use when doing prime factorization, but since this is the computer, I could only do it like the following above.)
