A number is written with the following factorization: 22 X 3 X 54 X 8 X 112. Is this factorization a prime
factorization? Explain why or why not. If it is not correct, give the correct prime factorization of the
number.

I didn't know
I need help please

hopefully i am right...
No it is not correct because 22,54,8 and 112 aren't prime numbersposted by anime lover

OK but why
posted by Princess

so, to get the correct factorization, factor all the nonprimes:
22 * 3 * 54 * 8 * 112
= 2*11*3*2*3^3*2^3*2^4*7
= 2^9 * 3^4 * 7 * 11posted by Steve

come on

all of the questions you keep asking have been answered above. I think you need to review what it means to be prime.

Look Princess, we went through this when you were trying to simplify fractions.
22 for example is 2 * 11
2 and 11 can not be factored any further. They are "prime"
then 44 = 2 * 22
that is NOT Enough (not prime factors)
because 22 can be factored as we know
so
44 = 2 * 2 * 11 that does it
now 2*2 is often written as two to the power two
or
2 * 2 = 2^2
so
44 = 2^2 * 11posted by Damon

This is not a prime factorization. 2 is prime, so is 3, and 5, as well as 11, but 8 is not prime. 8 can be broken down into 2^3.
Plug this back in. 2^2 x 3 x 5^4 x 2^3 x 11^2=2^5 x 3 x 5^4 x 11^2
