Solution

Para encontrar el número total de factores de 1440, primero descomponemos el número en sus factores primos.

  1. Descomposición en factores primos:
    • 1440 es divisible por 2: 1440 ÷ 2 = 720 720 ÷ 2 = 360 360 ÷ 2 = 180 180 ÷ 2 = 90 90 ÷ 2 = 45
    • 45 no es divisible por 2, pero sí por 3: 45 ÷ 3 = 15 15 ÷ 3 = 5
    • 5 es un número primo.

Entonces, la descomposición en factores primos de 1440 es: 1440=25×32×51 1440 = 2^5 \times 3^2 \times 5^1

  1. Para encontrar el número total de factores, utilizamos la fórmula que consiste en sumar 1 a cada uno de los exponentes de los factores primos y luego multiplicar los resultados:

    • Exponentes: 5, 2, 1
    • Sumamos 1 a cada exponente: (5+1), (2+1), (1+1)
    • Multiplicamos los resultados: 6 × 3 × 2
  2. Realizamos la multiplicación: 6×3=18 6 \times 3 = 18 18×2=36 18 \times 2 = 36

Por lo tanto, el número total de factores de 1440 es 36.
