Least Common Multiple of 66/45,128/69,914/249

Given numbers are 66/45,128/69,914/249

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 66,128,914

Least Common Multiple of Numerators i.e. LCM of 66,128,914 is 1930368.

GCF of Denominators means GCF of 45,69,249 as per the given fractions.

GCF of 45,69,249 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 66,128,914

LCM of Fractions 66/45,128/69,914/249 is 643456

2 66, 128, 914
33, 64, 457

∴ So the LCM of the given numbers is 2 x 33 x 64 x 457 = 1930368

Least Common Multiple of 66,128,914 with GCF Formula

Least Common Multiple of 66,128,914 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 66,128,914 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(66,128,914) = 2

common factors(in case of two or more numbers have common factors) = 2

GCF(66,128,914) x common factors =2 x 2 = 4

LCM(66,128,914) = ( 66 × 128 × 914 ) / 4

LCM(66,128,914) = 7721472 / 4

LCM(66,128,914) = 1930368


Lets's calculate GCF of 45,69,249

3 45, 69, 249
15, 23, 83

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1930368/3

Therefore the LCM of Fractions 66/45,128/69,914/249 is 643456
