Here we will show you step-by-step how to simplify 21/117 to the simplest form.
The key to solving this problem is to find the greatest common divisor of 21 and 117.
To find the greatest common divisor of 21 and 117, we list all of the factors of both numbers so we can compare the lists.
When we compared the factors of 21 (1, 3, 7, 21) and 117 (1, 3, 9, 13, 39, 117) we found that 3 is the largest factor that they have in common.
Since 3 is the largest common factor of 21 and 117, 3 is also the greatest common divisor of 21 and 117.
Now, we divide both the numerator and denominator in 21/117 by the greatest common divisor as follows:
Numerator: 21/3 = 7
Denominator: 117/3 = 39
Then, we put the numerator and denominator that we are left with back together to get our answer.
21/117 to the simplest form is:
7/39
