615. The millionth number with at least one million prime factors

Consider the natural numbers having at least 5 prime factors, which don't have to be distinct.
Sorting these numbers by size gives a list which starts with:

• 32=2⋅2⋅2⋅2⋅2
• 48=2⋅2⋅2⋅2⋅3
• 64=2⋅2⋅2⋅2⋅2⋅2
• 72=2⋅2⋅2⋅3⋅3
• 80=2⋅2⋅2⋅2⋅5
• 96=2⋅2⋅2⋅2⋅2⋅3
•   ...

So, for example, the fifth number with at least 5 prime factors is 80.
