F(40)
F(16)
Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
Prime factorization of 120 = 2^3 * 3 * 5
f(120) = 5
:
Prime factorization of 80 = 2^4 * 5
f(80) = 5
:
Prime factorization of 60 = 2^2 * 3 * 5
f(60) = 5
:
Prime factorization of 40 = 2^3 * 5
f(40) = 5
:
Prime factorization of 16 = 2^4
f(16) = 2
:
