First of all we need to notice that the product of the numbers yield such numbers which are too large for GRE officially provided calculator to handle,so we need to do some manipulations.
Dividing both sides by 810422 (it is a positive quantity & dividing both quantities by it does not disturb the quantitative comparison relationship between A & B )
we get
=> Quantity B > Quantity A hence the answer is B
Quantity A |
Quantity B |
810422*357289 |
736521*393245 |
