LCM of:

Least Common Multiple of 400/49,378/1670

Given numbers are 400/49,378/1670

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 400,378

Least Common Multiple of Numerators i.e. LCM of 400,378 is 75600.

GCF of Denominators means GCF of 49,1670 as per the given fractions.

GCF of 49,1670 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 400,378

LCM of Fractions 400/49,378/1670 is 75600

2 400, 378
200, 189

∴ So the LCM of the given numbers is 2 x 200 x 189 = 75600

Least Common Multiple of 400,378 with GCF Formula

Least Common Multiple of 400,378 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 400,378 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(400,378) = 2

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

GCF(400,378) x common factors =2 x 1 = 2

LCM(400,378) = ( 400 × 378 ) / 2

LCM(400,378) = 151200 / 2

LCM(400,378) = 75600


Lets's calculate GCF of 49,1670

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 75600/1

Therefore the LCM of Fractions 400/49,378/1670 is 75600
