Multiples of 18
Multiples of 18 are what you get when you multiply 18 by whole numbers. Common multiples of two numbers lead to the LCM.
Skip-counting keeps the last-digit rhythm of 18: the first ten multiples end in 8, 6, 4, 2, 0, 8, 6, 4, 2, 0. The first ten also pair to 198 in five pairs (18 + 180, 36 + 162, …) — the same numbers the multiplication table shows under other names. Every multiple shown keeps the even parity of 18 — the column never leaves it. The tenth multiple is the place-value shift: 180 is just 18 with a zero appended, since multiplying by ten always moves one place left. First common multiple with 2: 18, right here in row 1; with 3: 18 (row 1).
