LCM of 3, 4, and 5 is 60 — Here’s Why $ x = 57 $ Stands Out in Two-Digit Range (But Not 7, 8, or 9) In the fascinating world of number theory, least common multiples (LCM) unlock patterns that reveal how numbers relate. One simple yet insightful example involves finding the LCM of 3, 4, and 5 — a classic problem that leads to the number 60. Why does this matter? Because when testing two-digit integers like 57, this LCM connection highlights unique properties that set 57 apart — especially the fact that it avoids the digits 7, 8, and 9. Let’s break this down. ### Understanding LCM(3, 4, 5) = 60
