Solution

Para encontrar la factorización prima del número 84, sigamos estos pasos:

  1. Dividir 84 por el menor número primo:

    • 84 es divisible por 2 (el menor número primo).
    • 84 ÷ 2 = 42
  2. Dividir el resultado por el menor número primo:

    • 42 también es divisible por 2.
    • 42 ÷ 2 = 21
  3. Dividir el nuevo resultado por el siguiente número primo:

    • 21 no es divisible por 2, así que probamos con el siguiente número primo, que es 3.
    • 21 ÷ 3 = 7
  4. Verificar si el resultado es un número primo:

    • 7 es un número primo.

Entonces, la factorización prima de 84 es: 2, 2, 3, 7.

Dado que en la lista proporcionada (2, 2, 3) falta un factor primo, el factor primo que falta es 7.
