What value divided by 21 equals 21?

In other words, what would the dividend be if the divisor were 21 and the quotient 21?

To find the answer, just multiply the divisor with the quotient: 21 × 21 = 441

To prove this, let's compute 441 divided by 21: 441 21 = 21

How does it work?

Asking which value divided by 21 gives a result of 21 is equivalent to solving the following equation:

x 21 = 21

  1. We need to isolate x, so multiply both sides by 21: 21 x 21 = 21 × 21
  2. 21 x 21 is equivalent to 21 21 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 21 × 21 = 441

So, if the divisor is 21 and the quotient is 21, the dividend is 441.
