Write the number with the same number of decimal places first.

The most number of decimal places is

This makes comparing them much easier. Look at the units digits first: They are all

Look at the first decimal place next (tenths)

For the two remaining numbers - look at the second decimal place:

They are both

Now look at the third decimal place:

Now we can order the numbers from smallest to biggest:

Now you can write them as the original values.

The GCF of 8x and 2 is 2.

To find the GCF, first find the prime factorization of each term.

The prime factorization for 8x is 2, 2, 2, and x (those 4 terms multiply to equal 8x).

The prime factorization for 2 is 2 and 1.

To find the GCF of these two terms, multiply the common factor(s). In this case, since the only common factor is 2, that is the GCF.

Now divide each term by 2 and put the resulting expression within parentheses and put the 2 on the outside.

**Note** : This method of factorization, in which we first find identifiable factors and then proceed until all prime factors are known is called **tree method**. This is graphically described below.

A teacher will expect the prime number method. Just for the hell of it this is a different approach!

We have two numbers ; 24 and 7

I am going to count the 24's. However lets look at this value.

24 can be 'split' into a sum of 7's with a remainder. So each 24 consists of:

If we sum columns of these we will get the 3 summing to a value into which 7 will divide exactly. When this happens we have found our least common multiple.

REMEMBER WE ARE COUNTING THE 24's

We have a count of 7 so the value is
