How to simplify 4/21?

Simplifying a fraction (reducing it to the lowest terms), such as 4/21, means expressing the same value more clearly and concisely.

Step-by-step simplification of 4/21

  1. Start with computing the GCD of 4 and 21: GCD(4, 21) = 1.
  2. Divide the numerator by the GCD: 4/1 = 4
  3. Divide the denominator by the GCD: 21/1 = 21
  4. Combine these results to form the new simplified fraction: 4/21

The final result is: 4 21 = 4 21

Since the GCD is equal to 1, the fraction was already in its simplest form and couldn't be further reduced.
