There are infinitely many possible pairs.
Suppose X is ANY real number in the interval {-sqrt(42), sqrt(42)} and let Y = 42/X.
Then X*Y = X*42/X = 42.
Since the choice of X is arbitrary, there are infinitely many possible values for X. Furthermore, the restricted domain for X ensures that each (X, Y) pair is distinct.
There are, therefore, infinitely many possible answers.
2*21 = 42
The numbers are 6 and 28
1 x 42 2 x 21 3 x 14 6 x 7
-1 * 42 = -42 1 * -42 = -42 -2 * 22 = -42 2 * -22 = -42 -3 * 14 = -42 3 * -14 = -42 There are many ways to multiply two numbers to equal -42. However, one must be negative.
The 2 numbers that multiply together to equal 678 are 6 and 113.
2 when multiplied by 21 = 42
2*21 = 42
The numbers are 6 and 28
1 x 42 2 x 21 3 x 14 6 x 7
-1 * 42 = -42 1 * -42 = -42 -2 * 22 = -42 2 * -22 = -42 -3 * 14 = -42 3 * -14 = -42 There are many ways to multiply two numbers to equal -42. However, one must be negative.

As a product of its prime factors: 2*3*7 = 42
7 x 2 x 3 = 42
They are: 2*7*3 = 42
28/ 42 ; Multiply 7 on both and get 4/6 ; multiply both numbers by 2 and you get 2/3
They are: 37+5 = 42
6 / 7 2 / 21 3 / 14 1 / 42
