LCM(792/77, 990/3456) = 3960

Enter two or more fractions separated by **"commas"**

Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

Given numbers are 792/77,990/3456

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 792,990

Least Common Multiple of Numerators i.e. LCM of 792,990 is 3960.

GCF of Denominators means GCF of 77,3456 as per the given fractions.

GCF of 77,3456 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 792,990

2 | 792, 990 |

3 | 396, 495 |

3 | 132, 165 |

11 | 44, 55 |

4, 5 |

∴ So the LCM of the given numbers is 2 x 3 x 3 x 11 x 4 x 5 = 3960

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 792,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(792,990) = 198

common factors(in case of two or more numbers have common factors) = 1

GCF(792,990) x common factors =198 x 1 = 198

LCM(792,990) = ( 792 × 990 ) / 198

LCM(792,990) = 784080 / 198

LCM(792,990) = 3960

Lets's calculate GCF of 77,3456

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3960/1

Therefore the LCM of Fractions 792/77,990/3456 is 3960
