Question

Find the GCF and LCM of the following monomials 28,35 and 42 plz help!!

Answer 1

7 and 420 i think

Answer 2

write each number in prime factor form
28 = 2*2*7
35 = 5*7
42 = 2*3* 7

7 is the only factor common to all 3 so thats the GCF

LCM; choose one of the 3 7's, one 2 of two 2's, and 2,3 and 5
= 2*2*3*5*7 = 12*5*7 = 420
