What is 21/1 Simplified?

Answer: Fraction 21/1 simplified to lowest terms is 21/1

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

Since the numerator [21] is greater than the denominator [1] and numerator is a multiple of the denominator, so we can convert it into a whole number:

=21

Simplifying Fraction 21/1 using GCF

The first way to simplify the fraction 21/1 is to use the Greatest Common Factor (GCF) of our numerator [21] and denominator [1].

GCF of 21 and 1 is 1

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

21 ÷ 1

1 ÷ 1

Simplifying Fraction 21/1 using Prime Factors

Another method to reduce the fraction 21/1 to its simplest form is to use the Prime Factors of numerator [21] and denominator [1].

Prime Factors of 21: 3,7

Prime Factors of 1: 1

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

3 × 7

Simplifying Fraction 21/1 by Dividing by the Smallest Possible Number

In order to simplify our fraction we can start dividing both the numerator [21] and denominator [1] by the smallest possible number (2,3,4,5... and so on), and repeat this until it is impossible to divide without a reminder.

In our case (21/1) there is no possible numbers to divide our numerator and denominator.
