Least Common Multiple of 398/46,379/18,423/56

Given numbers are 398/46,379/18,423/56

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 398,379,423

Least Common Multiple of Numerators i.e. LCM of 398,379,423 is 63806166.

GCF of Denominators means GCF of 46,18,56 as per the given fractions.

GCF of 46,18,56 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 398,379,423

LCM of Fractions 398/46,379/18,423/56 is 31903083

Given numbers has no common factors except 1. So, there LCM is their product i.e 63806166

Least Common Multiple of 398,379,423 with GCF Formula

Least Common Multiple of 398,379,423 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 398,379,423 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(398,379,423) = 1

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

GCF(398,379,423) x common factors =1 x 1 = 1

LCM(398,379,423) = ( 398 × 379 × 423 ) / 1

LCM(398,379,423) = 63806166 / 1

LCM(398,379,423) = 63806166


Lets's calculate GCF of 46,18,56

2 46, 18, 56
23, 9, 28

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 63806166/2

Therefore the LCM of Fractions 398/46,379/18,423/56 is 31903083
