Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the highest amount of each factor. 2 x 3 x 5 x 7 = 210, the LCM
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.

How do you know if a number is a multiple of 7?
There is a trick to figuring out whether a number is divisible by 7, without having to divide it directly. Unfortunately, the 'shortcut' is almost as hard as simply doing the division in the first place.But for those who want to know, here's the trick:Take the final digit of the number.Double it.Subtract it from the rest of the digits.Repeat until you get a number that is (or isn't) a multiple of 7.For example, try 98:The final digit is 8.8 x 2 = 16.9 (98, without the 8) - 16 = -7.-7 is a multiple of 7, so 98 is divisible by 7.

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.
What is the common multiple of 120 and 149?
There are many common multiples of 120 and 149. A common multiple is simply a multiple of both numbers. The least common multiple is 120x149, since 149 is prime. (Note: this trick doesn't work on all pairs of number. Although the product is always a multiple, it's not the least common multiple.)
