Given numbers are 390/18,748/39,688/447

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 390,748,688

Least Common Multiple of Numerators i.e. LCM of 390,748,688 is 25087920.

GCF of Denominators means GCF of 18,39,447 as per the given fractions.

GCF of 18,39,447 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 390,748,688

LCM of Fractions 390/18,748/39,688/447 is 8362640

2 390, 748, 688
2 195, 374, 344
195, 187, 172

∴ So the LCM of the given numbers is 2 x 2 x 195 x 187 x 172 = 25087920

Least Common Multiple of 390,748,688 with GCF Formula

Least Common Multiple of 390,748,688 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 390,748,688 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(390,748,688) = 2

common factors(in case of two or more numbers have common factors) = 4

GCF(390,748,688) x common factors =2 x 4 = 8

LCM(390,748,688) = ( 390 × 748 × 688 ) / 8

LCM(390,748,688) = 200703360 / 8

LCM(390,748,688) = 25087920


Lets's calculate GCF of 18,39,447

3 18, 39, 447
6, 13, 149

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 25087920/3

Therefore the LCM of Fractions 390/18,748/39,688/447 is 8362640
