**Greatest Common Factor**

We found the factors 8,14,26,56 . The biggest common factor number is the **GCF** number.

So the **greatest common factor 8,14,26,56 ** is **2**.

Lets's calculate LCM of 21,28,30,98

2 | 21, 28, 30, 98 |

3 | 21, 14, 15, 49 |

7 | 7, 14, 5, 49 |

1, 2, 5, 7 |

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 2 x 5 x 7 = 2940

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2940

Therefore, the GCF of Fractions 8/21,14/28,26/30,56/98 is 2/2940

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 21,28,30,98 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,28,30,98) = 1

common factors(in case of two or more numbers have common factors) = 588

GCF(21,28,30,98) x common factors =1 x 588 = 588

LCM(21,28,30,98) = ( 21 × 28 × 30 × 98 ) / 588

LCM(21,28,30,98) = 1728720 / 588

LCM(21,28,30,98) = 2940

Here are some samples of GCF of Fractions calculations.
