So the **greatest common factor 9,28,42,48 ** is **1**.

Lets's calculate LCM of 27,36,45,56

2 | 27, 36, 45, 56 |

2 | 27, 18, 45, 28 |

3 | 27, 9, 45, 14 |

3 | 3, 9, 15, 14 |

1, 3, 5, 14 |

∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 1 x 3 x 5 x 14 = 7560

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7560

Therefore, the GCF of Fractions 9/27,28/36,42/45,48/56 is 1/7560

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 27,36,45,56 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(27,36,45,56) = 1

common factors(in case of two or more numbers have common factors) = 324

GCF(27,36,45,56) x common factors =1 x 324 = 324

LCM(27,36,45,56) = ( 27 × 36 × 45 × 56 ) / 324

LCM(27,36,45,56) = 2449440 / 324

LCM(27,36,45,56) = 7560

Here are some samples of GCF of Fractions calculations.
