Here we will show you step-by-step how to simplify 4/420 to the simplest form.
The key to solving this problem is to find the greatest common divisor of 4 and 420.
To find the greatest common divisor of 4 and 420, we list all of the factors of both numbers so we can compare the lists.
When we compared the factors of 4 (1, 2, 4) and 420 (1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420) we found that 4 is the largest factor that they have in common.
Since 4 is the largest common factor of 4 and 420, 4 is also the greatest common divisor of 4 and 420.
Now, we divide both the numerator and denominator in 4/420 by the greatest common divisor as follows:
Numerator: 4/4 = 1
Denominator: 420/4 = 105
Then, we put the numerator and denominator that we are left with back together to get our answer.
4/420 to the simplest form is:
1/105
