Lets's calculate LCM of 388,707,309

LCM of Fractions 388/98,707/48,309/78 is 42381822

Given numbers has no common factors except 1. So, there LCM is their product i.e 84763644

Least Common Multiple of 388,707,309 with GCF Formula

Least Common Multiple of 388,707,309 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 388,707,309 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(388,707,309) = 1

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

GCF(388,707,309) x common factors =1 x 1 = 1

LCM(388,707,309) = ( 388 × 707 × 309 ) / 1

LCM(388,707,309) = 84763644 / 1

LCM(388,707,309) = 84763644


Lets's calculate GCF of 98,48,78

2 98, 48, 78
49, 24, 39

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 84763644/2

Therefore the LCM of Fractions 388/98,707/48,309/78 is 42381822
