21
5

The fraction 21/5 is already in the simplest form, so it isn't possible to reduce it any further - numerator 21 and denominator 5 have no common factors other than 1 (one)

Since the numerator [21] is greater than the denominator [5] of the fraction (it's called an improper fraction), so we can convert it into a mixed fraction with a whole number:

21
5
= 4
1
5

Simplifying Fraction 21/5 using GCF

The first way to simplify the fraction 21/5 is to use the Greatest Common Factor (GCF) of our numerator [21] and denominator [5].

GCF of 21 and 5 is 1

And then divide both the numerator [21] and denominator [5] by the GCF [1].

21 ÷ 1
5 ÷ 1
=
21
5

Simplifying Fraction 21/5 using Prime Factors

Another method to reduce the fraction 21/5 to its simplest form is to use the Prime Factors of numerator [21] and denominator [5].

Prime Factors of 21: 3,7

Prime Factors of 5: 5

Now we can write down a new fraction expressed by its Prime Factors and cancel common factors in numerator and denominator:

3 × 7
5
=
21
5

Simplifying Fraction 21/5 by Dividing by the Smallest Possible Number

In order to simplify our fraction we can start dividing both the numerator [21] and denominator [5] by the smallest possible number (2,3,4,5... and so on), and repeat this until it is impossible to divide without a remainder.

In our case (21/5) there are no possible numbers to divide our numerator and denominator.
