is 11! divisible by 7? Explain why or why not

OpenStudy (anonymous):

yes it is, cos there is a factor of "7" in the evaluation

OpenStudy (anonymous):

could you show some work please?

OpenStudy (anonymous):

\[\frac{11*10*9*8*7*6....}{7}\]

OpenStudy (anonymous):

see that factor of "7" on the top and bottom?

OpenStudy (anonymous):

no, it says math processing error

OpenStudy (anonymous):

and the answer to that is, 11*10*9*8*6*5*4*3*2*1 (product of all number from 11 to 1 except for 7)

OpenStudy (anonymous):

so, the answer is yes because 7 is a factor being multiplied to get the answer?

OpenStudy (anonymous):

yep

OpenStudy (anonymous):

okay thanks.

OpenStudy (anonymous):

\[ \frac{11\times10\times9\times8\times7\times6\times5\times4\times3\times2\times1}{7} \]
