Least Common Multiple of 21/997,750/381,128/196

Given numbers are 21/997,750/381,128/196

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 21,750,128

Least Common Multiple of Numerators i.e. LCM of 21,750,128 is 336000.

GCF of Denominators means GCF of 997,381,196 as per the given fractions.

GCF of 997,381,196 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,750,128

LCM of Fractions 21/997,750/381,128/196 is 336000

2 21, 750, 128
3 21, 375, 64
7, 125, 64

∴ So the LCM of the given numbers is 2 x 3 x 7 x 125 x 64 = 336000

Least Common Multiple of 21,750,128 with GCF Formula

Least Common Multiple of 21,750,128 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 21,750,128 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,750,128) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(21,750,128) x common factors =1 x 6 = 6

LCM(21,750,128) = ( 21 × 750 × 128 ) / 6

LCM(21,750,128) = 2016000 / 6

LCM(21,750,128) = 336000


Lets's calculate GCF of 997,381,196

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 336000/1

Therefore the LCM of Fractions 21/997,750/381,128/196 is 336000
