There are five natural numbers with the largest number of divisors within 100. What are they?
① If there is exactly one prime factor, then the greatest number of divisors is 26 = 64, 6 + 1 = 7, and 64 has 7 divisors. ② if there are exactly two different prime factors, then the greatest number of divisors is 23 × 32 = 72 and 25 × 3 = 96, and (3 + 1) × (2 + 1) = 12 (5 + 1) × (1 + 1) = 1272 and 96 have 12 divisors respectively
