Tricks to finding a GCF of one number?
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.
What is the trick to finding the lowest common multiple?
Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Combine the factors, eliminating duplicates. 2 x 3 x 5 x 7 = 210, the LCM

I whole and 3 over 4 minus 7 over 8?
The trick here - apart from the usual one, of finding a common denominator - is to "lend" one from the whole part, and add it to the fraction. Since one whole is 3/4, you add 4/4, to get 7/4. Then (and after converting everything to the common denominator), you can easily subtract the fractional part.
What is the LCM of 30 43?
This is a trick question. When referring to the Lowest Common Multiple, you are comparing two numbers and finding the lowest multiple that they both have in common. As there is only 1 number, it isn't comparing it. The LCM of 43 and itself would be 43, because 43 is a multiple of itself.

You have to make a common denominator between them, otherwise you can't.
