For example, if you're looking for a factor pair that includes 13: Start with 12: 420 ÷ 12 = 35 35 - 12 = 23 (not 13, so keep going) Try 14: 420 ÷ 14 = 30 30 - 14 = 16 (still not 13) Finally, test 15: 420 ÷ 15 = 28 28 - 15 = 13 (found the correct pair: 15 × 28 = 420) This method helps you quickly zero in on the right factors without listing them all manually.
