Correct answer: B
Step-by-Step Solution
To find the total number of factors for any integer, use its prime factorization.
Perform Prime Factorization:
Break down 9600 into prime factors:
9600 = 96 * 100
96 = 32 * 3 = 2^5 * 3
100 = 10 * 10 = (2 * 5) * (2 * 5) = 2^2 * 5^2
Combine them: 9600 = (2^5 * 3) * (2^2 * 5^2)
9600 = 2^7 * 3^1 * 5^2
Apply the Factor Counting Formula:
If a number is expressed as n = (p^a) * (q^b) * (r^c)..., the total number of factors is (a + 1) * (b + 1) * (c + 1)...
Here, the exponents are 7, 1, and 2.
Total factors = (7 + 1) * (1 + 1) * (2 + 1)
Total factors = 8 * 2 * 3
Total factors = 48.
