LCM of:

Least Common Multiple of 56/690,65/390,646/238

Given numbers are 56/690,65/390,646/238

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 56,65,646

Least Common Multiple of Numerators i.e. LCM of 56,65,646 is 1175720.

GCF of Denominators means GCF of 690,390,238 as per the given fractions.

GCF of 690,390,238 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 56,65,646

LCM of Fractions 56/690,65/390,646/238 is 587860

2 56, 65, 646
28, 65, 323

∴ So the LCM of the given numbers is 2 x 28 x 65 x 323 = 1175720

Least Common Multiple of 56,65,646 with GCF Formula

Least Common Multiple of 56,65,646 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 56,65,646 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(56,65,646) = 1

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

GCF(56,65,646) x common factors =1 x 2 = 2

LCM(56,65,646) = ( 56 × 65 × 646 ) / 2

LCM(56,65,646) = 2351440 / 2

LCM(56,65,646) = 1175720


Lets's calculate GCF of 690,390,238

2 690, 390, 238
345, 195, 119

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1175720/2

Therefore the LCM of Fractions 56/690,65/390,646/238 is 587860
