Parity and primality

Parity
Even

Divisible by 2.

Prime
No

Composite — it factors as 2^10.

1 distinct prime factor, 10 with multiplicity.

Squarefree
No

At least one prime appears squared.

Prime power
2^10

A single prime raised to a power.

Powerful
Yes

Every prime factor appears at least squared.

Möbius μ(n)
