Zero. Zero times anything equals zero.

7 and 13. Solution : Let the two numbers be a and b. Then ab = 91 , so b = 91/a. a + b = 20 .......substituting for b, this becomes : a + (91/a) =20 Multiplying both sides by a gives : a2 + 91 = 20a Rearranging : a2 - 20a + 91 = 0 Factoring gives : (a - 7)(a - 13) = 0 Then the numbers occur when x - 7 = 0. → x = 7, and when x - 13 = 0. → x = 13.
The factors of 784 are 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, and 784. The prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7.
