6 and 90
40 and 50
45 and 10
45 and 10
15 and 90
The set of (90,90) has a GCF and an LCM of 90.The set of (-90,-90) has a GCF and an LCM of 90.
15 and 18
90 and 180 have a GCF of 90.
126 and 90 (trial and error gets you the answer)
40 and 50
10 and 45. 10=5*2 10+45=55 45*2=90 45=5*9 10*9=90

In these types of problems, the numbers can also be the answer. 3 and 30 have a GCF of 3 and an LCM of 30. Since the product of the GCF and LCM of two numbers is the same as the product of the numbers, you could also use another factor pair of 90, like 6 and 15.
