Answer:
30(3+2)
Step-by-step explanation:
90=3(30)=3(3)(10)=3(3)(2)(5)
60=3(20)=3(5)(4)=3(2)(2)(5)
The factors that 90 and 60 have in common are a pair of 3,2, and 5's.
So the biggest factor we can factor out is 3*2*5 which is 30
So 30(3+2)
Leftovers from the prime factorizations above stayed in the ( )
