LCM of:

Least Common Multiple of 405/14,638/9290

Given numbers are 405/14,638/9290

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 405,638

Least Common Multiple of Numerators i.e. LCM of 405,638 is 258390.

GCF of Denominators means GCF of 14,9290 as per the given fractions.

GCF of 14,9290 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 405,638

LCM of Fractions 405/14,638/9290 is 129195

Given numbers has no common factors except 1. So, there LCM is their product i.e 258390

Least Common Multiple of 405,638 with GCF Formula

Least Common Multiple of 405,638 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 405,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(405,638) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(405,638) x common factors =1 x 1 = 1

LCM(405,638) = ( 405 × 638 ) / 1

LCM(405,638) = 258390 / 1

LCM(405,638) = 258390


Lets's calculate GCF of 14,9290

2 14, 9290
7, 4645

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 258390/2

Therefore the LCM of Fractions 405/14,638/9290 is 129195
