In a certain game, a large container is filled with red, yellow, green, and blue beads worth, respectively, 7, 5, 3, and 2 points each. A number of beads are then removed from the container. If the product of the point values of the removed beads is 147,000, how many red beads were removed?

(A) 5
(B) 4
(C) 3
(D) 2
(E) 0

$$147,000=2^3*3*5^3*7^2$$.

Since no other beads value is a multiple of 7, then there must be two red beads removed.

Similar question to practice: http://gmatclub.com/forum/in-a-certain- ... 26425.html

Hope it helps.

Bunuel how did you get this $$147,000=2^3*3*5^3*7^2$$.

147 is divisable by 7 then we get 21
21 is divisible by 3
we get 7

so total we TWO 7s and ONE 3

It's 147000, so one hundred forty-seven thousand...
