Know Least Common Multiple of fractions 15/24, 20/28, 25/32 quickly i.e. 75 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.

Least Common Multiple (LCM) of 15/24, 20/28, 25/32 is **75**.

LCM(15/24, 20/28, 25/32) = 75

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

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

Given numbers are 15/24,20/28,25/32

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 15,20,25

Least Common Multiple of Numerators i.e. LCM of 15,20,25 is 300.

GCF of Denominators means GCF of 24,28,32 as per the given fractions.

GCF of 24,28,32 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 15,20,25

5 | 15, 20, 25 |

3, 4, 5 |

∴ So the LCM of the given numbers is 5 x 3 x 4 x 5 = 300

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 15,20,25 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(15,20,25) = 5

common factors(in case of two or more numbers have common factors) = 5

GCF(15,20,25) x common factors =5 x 5 = 25

LCM(15,20,25) = ( 15 × 20 × 25 ) / 25

LCM(15,20,25) = 7500 / 25

LCM(15,20,25) = 300

Lets's calculate GCF of 24,28,32

2 | 24, 28, 32 |

2 | 12, 14, 16 |

6, 7, 8 |

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 300/4

Therefore the LCM of Fractions 15/24,20/28,25/32 is 75
