What's the Least Common Multiple (LCM) of 42 and 100?
Answer
LCM of 42 and 100 is
2,100
First common multiples: 2,100; 4,200; 6,300; …
2,100 is divisible by both: 2,100 ÷ 42 = 50; 2,100 ÷ 100 = 21 — and 50 and 21 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/42 by 50 and of y/100 by 21.
42 = 2 × 3 × 7
100 = 22 × 52
| Prime | 42 | 100 | Highest power |
|---|---|---|---|
| 2 | 2 | 22 | 22 |
| 3 | 3 | — | 3 |
| 5 | — | 52 | 52 |
| 7 | 7 | — | 7 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
LCM = 22 × 3 × 52 × 7 = 2,100
