What's the Least Common Multiple (LCM) of 72 and 99?
Answer
LCM of 72 and 99 is
792
First common multiples: 792; 1,584; 2,376; …
792 is divisible by both: 792 ÷ 72 = 11, 792 ÷ 99 = 8 — and 11 and 8 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/72 by 11 and of y/99 by 8.
72 = 23 × 32
99 = 32 × 11
| Prime | 72 | 99 | Highest power |
|---|---|---|---|
| 2 | 23 | — | 23 |
| 3 | 32 | 32 | 32 |
| 11 | — | 11 | 11 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
LCM = 23 × 32 × 11 = 792
