Examples of Factors
Example 1
Find the factor of
First, we will find the numbers that multiplied together will result to
Let’s start with times is equals to
Then, times is
Therefore, the factors of are:
Example 2
Find the factors of
First, we will find the numbers that multiplied together will result to
Let’s start with times is equals to
Then, times is
And lastly, times is
Therefore, the factors of are:
Examples of Greatest Common Factor (GCF)
Example 1
GCF of and
First, list the factors of and
Now we have,
Therefore, the Greatest Common Factor is
Example 2
GCF of and
First, list the factors of and
Now we have,
Therefore, the Greatest Common Factor is
Examples of Multiples
Example 1
Multiples of
In order to find the mutiples, we must multiply by an integer (not a fraction)
Therefore the multiples og are ,…..
Example 2
Multiples of
In order to find the mutiples, we must multiply by an integer (not a fraction)
Therefore the multiples og are ,…..
Least Common Multiple (LCM)
Example 1
Least Common Multiple (LCM) of and
First, list down the multiples of each number
Then, the first mutiple that occurs on both numbers is the LCM
Therefore, the LCM is
Example 2
Least Common Multiple (LCM) of and
First, list down the multiples of each number
Then, the first mutiple that occurs on both numbers is the LCM
Therefore, the LCM is
