327.7081 is terminating decimal number. So, it represents a rational number and also its denominator must have the form `2^(m)xx5^(n)`
Thus, 327.7081= `(3277081)/(10000)=(p)/(q)`
`therefore q=10^(4)=2 xx 2 xx 2 xx 2 5 xx 5 xx 5 xx 5`
` =2^(4)xx5^(4)=(2 xx 5)^(4)`
Hence, the prime factors of q is 2 and 5.
