Hi there!

I didn't get the answer right, because neither 120, nor 240 include the factor 7. Why do we just focus on the exponential term of 2 and not on the 7?
Thank you very much for your response.

5*4*3= 120
240=5*4*3*2
hence 7*6*5*4*3 is not divisible by 240

Thank you very much for your response.


The question is: \(3*4*5*6*7=2^3*3^2*5*7\) is divisible by all of the following EXCEPT... So, \(2^3*3^2*5*7\) is dividend and the options are divisors, not vise-versa.

\(2^3*3^2*5*7\) is NOT divisible only by \(240=2^4*3*5\), because the power of 2 in the divisor is higher than the power of 2 in dividend.

Hope it's clear.

Eliminate 0 in all options and 5*2 in multiple to get

7*3*2*2*3

12=3*2*2, Yes
24=2*2*2*3, No
36=2*3*3*2, Yes
84=2*7*3*2, Yes
126=2*7*3*3, Yes
