Least Common Multiple of 578/28,435/7720

Given numbers are 578/28,435/7720

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 578,435

Least Common Multiple of Numerators i.e. LCM of 578,435 is 251430.

GCF of Denominators means GCF of 28,7720 as per the given fractions.

GCF of 28,7720 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 578,435

LCM of Fractions 578/28,435/7720 is 251430/4

Given numbers has no common factors except 1. So, there LCM is their product i.e 251430

Least Common Multiple of 578,435 with GCF Formula

Least Common Multiple of 578,435 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 578,435 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(578,435) = 1

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

GCF(578,435) x common factors =1 x 1 = 1

LCM(578,435) = ( 578 × 435 ) / 1

LCM(578,435) = 251430 / 1

LCM(578,435) = 251430


Lets's calculate GCF of 28,7720

2 28, 7720
2 14, 3860
7, 1930

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 251430/4

Therefore the LCM of Fractions 578/28,435/7720 is 251430/4
