Least Common Multiple of 21/520,165/408,618/964

Given numbers are 21/520,165/408,618/964

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 21,165,618

Least Common Multiple of Numerators i.e. LCM of 21,165,618 is 237930.

GCF of Denominators means GCF of 520,408,964 as per the given fractions.

GCF of 520,408,964 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,165,618

LCM of Fractions 21/520,165/408,618/964 is 237930/4

3 21, 165, 618
7, 55, 206

∴ So the LCM of the given numbers is 3 x 7 x 55 x 206 = 237930

Least Common Multiple of 21,165,618 with GCF Formula

Least Common Multiple of 21,165,618 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 21,165,618 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,165,618) = 3

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

GCF(21,165,618) x common factors =3 x 3 = 9

LCM(21,165,618) = ( 21 × 165 × 618 ) / 9

LCM(21,165,618) = 2141370 / 9

LCM(21,165,618) = 237930


Lets's calculate GCF of 520,408,964

2 520, 408, 964
2 260, 204, 482
130, 102, 241

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 237930/4

Therefore the LCM of Fractions 21/520,165/408,618/964 is 237930/4
