Here we will show you step-by-step how to simplify 21/105 to the simplest form.
The key to solving this problem is to find the greatest common divisor of 21 and 105.
To find the greatest common divisor of 21 and 105, 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 105 (1, 3, 5, 7, 15, 21, 35, 105) we found that 21 is the largest factor that they have in common.
Since 21 is the largest common factor of 21 and 105, 21 is also the greatest common divisor of 21 and 105.
Now, we divide both the numerator and denominator in 21/105 by the greatest common divisor as follows:
Numerator: 21/21 = 1
Denominator: 105/21 = 5
Then, we put the numerator and denominator that we are left with back together to get our answer.
21/105 to the simplest form is:
1/5
