Tips: Get an actual book and wright the questions down and then answer them because you can work out freely and use as much space! For help some online y0utubers like 'Math Antics' and 'The Chemistry Tutor' (best choice is math antics for stuff like this and harder stuff use the chemistry tutor) to help you!

GCF formula: The greatest common factor is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.

LCM formula: First, list the first several multiples of each number. Then just look for multiples common to both lists. If there are no common multiples in the lists, write out additional multiples for each number. Then we look for the smallest number that is common to both lists. This number is the LCM.

Prime Factorization Formula:

1) Divide the given number by the smallest prime number. eg. if the given number is 9, the smallest prime number that is divisible by 9 is 3 (don't use 1). The only time you divide by 1 is when there is no other prime number to divide by. For example if you want to find the prime factorization of 3, the only smallest prime number is 1. Thus, 3 is written as 1 × 3. Therefore, the prime factorization of 3 is 1 × 3 or 3. Note: If a number in the pair factor is composite, split the composite number into its prime factors, and write the numbers in the form of the product of its prime factors.

Step 2: Again, divide the quotient by the smallest prime number. (basically do the same process if the number is divisible. Like since we ended up with 3, you can't divide it anymore other than 1 so we just leave it as 3.)

Step 3: Repeat the process, until the quotient becomes 1. (Do the same thing again and again. In our case, the quotient is already a 1.)

Step 4: Finally, multiply all the prime factors. eg. Ours is 3x3 which equals 9! If you want, you can add a 1 but in reality it makes no difference. Like it could be 1x3x1x3 which equals 9 but 3x3 also equals 3. The best way to work it out is using a factor tree. (refer below)
