There is an infinite number of pairs of multiplicands which yield the product 343, one of which is 1 x 343.
7 x 7 x 7 = 343
7
7 exponent 3 = 343
49 x 7
You are asking for the square root of 117649 - which is 343 (which you could get by using the square root function on most calculators).
7 x 7 x 7 = 343
2445
The solution is to divide 343 by the square root of 2... That will give you the missing number.
2 x 343 = 686
The factor pairs of 1029 are: 1 × 1029 3 × 343 7 × 147 21 × 49
The answer equals 343
