## mathsucksalot123 Group Title find the prime factorization of 11! one year ago one year ago

1. satellite73 Group Title

first write it all out, then factor the numbers that are not prime

2. mathsucksalot123 Group Title

wouldn't u factor the numbers that are prime

3. satellite73 Group Title

you cannot factor a prime number that is why it is called prime

4. mathsucksalot123 Group Title

so ur saying the answer is all of the composite numbers? what?

5. satellite73 Group Title

start with $11\times 10\times 9\times 8\times 7\times 6\times 5\times 4\times 3\times 2$

6. satellite73 Group Title

then factor the numbers that can be factored, like for example $$10=5\times 2$$

7. mathsucksalot123 Group Title

so it would be 2,3,4,5

8. mathsucksalot123 Group Title

or 2x3x5

9. satellite73 Group Title

something like the second one

10. satellite73 Group Title

you have a lot more work to do you have to factor all the numbers that you can

11. mathsucksalot123 Group Title

i think i did...i showed the work on my paper

12. electrokid Group Title

$11!=2^\text{number of even terms +1}\times3^\text{number of terms divisible by 3+1}\\ \qquad\times5^\text{no. of terms divisible by 5}\times7^{1}\times11^{1}$

13. electrokid Group Title

so, $11!=2^8\times3^4\times5^2\times7\times11$
