Given numbers are 21/438,668/678,219/215

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 21,668,219

Least Common Multiple of Numerators i.e. LCM of 21,668,219 is 1024044.

GCF of Denominators means GCF of 438,678,215 as per the given fractions.

GCF of 438,678,215 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,668,219

LCM of Fractions 21/438,668/678,219/215 is 1024044

3 21, 668, 219
7, 668, 73

∴ So the LCM of the given numbers is 3 x 7 x 668 x 73 = 1024044

Least Common Multiple of 21,668,219 with GCF Formula

Least Common Multiple of 21,668,219 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 21,668,219 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,668,219) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(21,668,219) x common factors =1 x 3 = 3

LCM(21,668,219) = ( 21 × 668 × 219 ) / 3

LCM(21,668,219) = 3072132 / 3

LCM(21,668,219) = 1024044


Lets's calculate GCF of 438,678,215

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1024044/1

Therefore the LCM of Fractions 21/438,668/678,219/215 is 1024044
