What is the answer to Question 6 ‘If the LCM of 18 and p is 90, which of the following must be the LCM of p and 108?’ Is it option (D) 540? This question pops up @ 1:30:49 and vanishes. It would be great if you tell the answer!
You are right. Saquib immediately moved to the next question. This question isn't discussed on GMAT Club forums either. Why don't you post it on the forum and seek feedback from peers?
please take more classes, a humble request
Thanks for the session!

@52:37 If i subsititute b=ka in (2), i get k^2=a+1. Hence Int=Int. Hence B should be sufficient?
Sir thanks for the video session. I got great interaction & understanding 👍

in q4, choice A tells us that n^3 has 7 factors (odd no. of factors) , then n^3 must be a perfect square, so n^3 could be 64, and therefore n=4.
sir, great session, one question is o multiple of 6 or for that matter any number? should it be counted?
Yes 0 is the multiple of all numbers, and 1 is a factor of all numbers.
CHOSE E. WRONG. MAKE CASES.
