Least Common Multiple of 428/81,244/7680

Given numbers are 428/81,244/7680

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 428,244

Least Common Multiple of Numerators i.e. LCM of 428,244 is 26108.

GCF of Denominators means GCF of 81,7680 as per the given fractions.

GCF of 81,7680 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 428,244

LCM of Fractions 428/81,244/7680 is 26108/3

2 428, 244
2 214, 122
107, 61

∴ So the LCM of the given numbers is 2 x 2 x 107 x 61 = 26108

Least Common Multiple of 428,244 with GCF Formula

Least Common Multiple of 428,244 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 428,244 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(428,244) = 4

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

GCF(428,244) x common factors =4 x 1 = 4

LCM(428,244) = ( 428 × 244 ) / 4

LCM(428,244) = 104432 / 4

LCM(428,244) = 26108


Lets's calculate GCF of 81,7680

3 81, 7680
27, 2560

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 26108/3

Therefore the LCM of Fractions 428/81,244/7680 is 26108/3
