Here we will show you step-by-step how to simplify 20/642 to the simplest form.
The key to solving this problem is to find the greatest common divisor of 20 and 642.
To find the greatest common divisor of 20 and 642, we list all of the factors of both numbers so we can compare the lists.
When we compared the factors of 20 (1, 2, 4, 5, 10, 20) and 642 (1, 2, 3, 6, 107, 214, 321, 642) we found that 2 is the largest factor that they have in common.
Since 2 is the largest common factor of 20 and 642, 2 is also the greatest common divisor of 20 and 642.
Now, we divide both the numerator and denominator in 20/642 by the greatest common divisor as follows:
Numerator: 20/2 = 10
Denominator: 642/2 = 321
Then, we put the numerator and denominator that we are left with back together to get our answer.
20/642 to the simplest form is:
10/321
