Question

Use the digits 1,3,4 and 7 to create two whole numbers whose product is estimated to be about 600

Answer 1

If you are looking for an exact 600 I don't think you will get it.

Here's one answer

13 * 47 = 611 Answer

The answer is about 600.

Is there anything better?

147 * 3 is too small. (441)

43*17 = 731 which is too large.
