3 and 30
You can find the GCF of two numbers by dividing their product by their LCM. The LCM of 30 and 42 is 210. What is their GCF? 30 x 42 = 1260 divided by 210 = 6 The GCF of 30 and 42 is 6.

30 and 40

2 and 15
They are: gcf = 15 and LCM = 30
The GCF is 10. The LCM is 30.
To have either an LCM (Least Common Multiple) or GCF (Greatest Common Factor), you must have two or more numbers.
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.
