Least Common Multiple of 320/46,478/38,738/21

Given numbers are 320/46,478/38,738/21

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 320,478,738

Least Common Multiple of Numerators i.e. LCM of 320,478,738 is 28221120.

GCF of Denominators means GCF of 46,38,21 as per the given fractions.

GCF of 46,38,21 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 320,478,738

LCM of Fractions 320/46,478/38,738/21 is 28221120

2 320, 478, 738
160, 239, 369

∴ So the LCM of the given numbers is 2 x 160 x 239 x 369 = 28221120

Least Common Multiple of 320,478,738 with GCF Formula

Least Common Multiple of 320,478,738 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 320,478,738 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(320,478,738) = 2

common factors(in case of two or more numbers have common factors) = 2

GCF(320,478,738) x common factors =2 x 2 = 4

LCM(320,478,738) = ( 320 × 478 × 738 ) / 4

LCM(320,478,738) = 112884480 / 4

LCM(320,478,738) = 28221120


Lets's calculate GCF of 46,38,21

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 28221120/1

Therefore the LCM of Fractions 320/46,478/38,738/21 is 28221120
