How to Calculate Factor Pairs of 402
Step-by-Step Process
To find all factor pairs of 402, we need to identify all integers that divide 402 evenly (with no remainder).
- Start with the smallest factor, which is always 1
- Check each integer from 1 up to the square root of 402 (v402 ≈ 20.05)
- For each factor found, its corresponding pair is calculated by dividing 402 by that factor
