A number where some but not all prime factors have multiplicity above 1 is neither square-free nor squareful. The Liouville function λ(n) is 1 if Ω(n) is even, and is -1 if Ω(n) is odd. The Möbius function μ(n) is 0 if n is not square-free. Otherwise μ(n) is 1 if Ω(n) is even, and is −1 if Ω(n) is odd. A sphenic number has Ω(n) = 3 ...
The sum of its factors (including one and itself) sum to 360, exactly three times 120. Perfect numbers are order two ( 2-perfect ) by the same definition. 120 is the sum of a twin prime pair (59 + 61) and the sum of four consecutive prime numbers (23 + 29 + 31 + 37), four consecutive powers of two (8 + 16 + 32 + 64), and four consecutive powers ...
For n greater than 1, both + and are greater than 4, so removing the factor of 8 (which is equivalent to removing the factor 4 from + or , and removing the factor 2 from the other number) still leaves two factors greater than 1. Therefore, the number cannot be prime.

Levy noted that The Lions anticipate serving 1,800 turkey legs — and 3,500 pounds of turkey in all — while also dishing up 3,000 pounds of mashed potatoes, 2,000 pounds of stuffing, 700 pounds ...
The square-free part is 7, the square-free factor such that the quotient is a square is 3 ⋅ 7 = 21, and the largest square-free factor is 2 ⋅ 3 ⋅ 5 ⋅ 7 = 210. No algorithm is known for computing any of these square-free factors which is faster than computing the complete prime factorization.
