Factoring numbers into product of primes
Hey guys, need to confirm my answers for these following question.

Factoring the following numbers into the product of primes:

a) $27$

My Answer:

= $27 \cdot 1$

b) $1024$

My Answer:

= $2^{10}$

c) $625000$

My Answer:

= $2^3 \cdot 5^7$

d) $12!$ (Also equals 479001600)

My Answer:

= $2^{10} \cdot 3^5 \cdot 5^2 \cdot 7 \cdot 11$

Are my answers correct according to what the question is asking? thanks
