Least Common Multiple of 840/84,388/2708

Given numbers are 840/84,388/2708

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 840,388

Least Common Multiple of Numerators i.e. LCM of 840,388 is 81480.

GCF of Denominators means GCF of 84,2708 as per the given fractions.

GCF of 84,2708 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 840,388

LCM of Fractions 840/84,388/2708 is 20370

2 840, 388
2 420, 194
210, 97

∴ So the LCM of the given numbers is 2 x 2 x 210 x 97 = 81480

Least Common Multiple of 840,388 with GCF Formula

Least Common Multiple of 840,388 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 840,388 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(840,388) = 4

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

GCF(840,388) x common factors =4 x 1 = 4

LCM(840,388) = ( 840 × 388 ) / 4

LCM(840,388) = 325920 / 4

LCM(840,388) = 81480


Lets's calculate GCF of 84,2708

2 84, 2708
2 42, 1354
21, 677

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 81480/4

Therefore the LCM of Fractions 840/84,388/2708 is 20370
