o determine what equals 16 in multiplication, consider all the pairs of numbers that multiply together to give 16. These are known as factor pairs of 16:
- 1 × 16 = 16
- 2 × 8 = 16
- 4 × 4 = 16
These pairs include both positive and negative numbers because multiplying two negative numbers also gives a positive result:
- (-1) × (-16) = 16
- (-2) × (-8) = 16
- (-4) × (-4) = 16
Thus, the factor pairs of 16 are (1, 16), (2, 8), and (4, 4) in positive numbers, and their negative counterparts. Multiplication with these pairs will always yield 16.
