what is a number that is less that 250 has one of its prime factors is a exponent of 4 and when expressed in exponential form its prime factorization has 3 basses

if one factor is a power of 4, then it must be 4,16 or 64

"no idea what 3 basses" are
but it sounds like maybe its prime factors are 2,3,5
64*2*5 = 640 is too big, but
16*3*5 = 240, which is less than 250
