Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 14, 21, 42 i.e. 42 smallest integer divisible by all numbers.

Least common multiple (LCM) of 14, 21, 42 is **42**.

LCM(14, 21, 42) = 42

*Least common multiple* or lowest common denominator (lcd) can be calculated in three ways

- Least Common Multiple of 14, 21, 42 by common division method
- Least Common Multiple of 14, 21, 42 with GCF Formula

2 | 14, 21, 42 |

3 | 7, 21, 21 |

7 | 7, 7, 7 |

1, 1, 1 |

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 1 x 1 = 42

The formula of **LCM** is LCM(a_{1},a_{2},a_{3}....,a_{n}) = ( a_{1} × a_{2} × a_{3} × .... × a_{n}) / GCF(a_{1},a_{2},a_{3}....,a_{n}) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 14,21,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(14,21,42) = 7

common factors(in case of two or more numbers have common factors) = 42

GCF(14,21,42) x common factors =7 x 42 = 294

LCM(14,21,42) = ( 14 × 21 × 42 ) / 294

LCM(14,21,42) = 12348 / 294

LCM(14,21,42) = 42

∴ Least Common Multiple of 14,21,42 is 42
