An interesting trick is to subtract the two numbers, as follows:
For example, the GCF of 14 and 10 is the same as the GCF of 10 and 4, where 4 is the result of the subtraction. Instead of subtracting several times, you can also get the remainder of a division: 10 divided by 4 gives a remainder of 2.

The answer is 63.LCM of 63 and 66 is 1386.GCF of 63 and 66 is 3. Given one number A, the formula for finding B, the unknown number, is : (LCM/A) x GCF = B (1386/66) x 3 = 21 x 3 = 63
The product of the original numbers is equal to the product of the GCF and LCM. Divide the product of the LCM and GCF by the one number. The answer will be the other.
The GCF refers to integers, not fractions.
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.
There is no common factor for one number. A common factor can be found between one or more numbers. For example, the GCF of 30 and 48 is 6.
