Question
Find the prime factorization of the number 84.One of the prime factors is missing from the following list:2, 2, 3What is the missing prime factor?
Solution
Para encontrar la factorización prima del número 84, sigamos estos pasos:
-
Dividir 84 por el menor número primo:
- 84 es divisible por 2 (el menor número primo).
- 84 ÷ 2 = 42
-
Dividir el resultado por el menor número primo:
- 42 también es divisible por 2.
- 42 ÷ 2 = 21
-
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
-
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.
