Question 704890: use the digits 2, 3, 5 and 7 so the product is 945. need to show work

No. You cannot use 2. If 2 is a factor, the product WILL be even. Any integer ending in 5 is odd. Try completely factoring 945 and you will see. You first find 5*9*21, and then..., 5*3*3*3*7. There is no "2" and there is no "7".
