If \(p^3\) is divisible by 80, the least +ve value of \(p\) can be 20
No of distinct factors for 20 = 3 * 2 = 6 (1, 2, 4, 5, 10, 20)
so \(p\) must have at least 6 distinct factors.
Answer C
No of distinct factors for 20 = 3 * 2 = 6 (1, 2, 4, 5, 10, 20)
so \(p\) must have at least 6 distinct factors.
