Least Common Multiple of 690/247,121/690,145/102

Given numbers are 690/247,121/690,145/102

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 690,121,145

Least Common Multiple of Numerators i.e. LCM of 690,121,145 is 2421210.

GCF of Denominators means GCF of 247,690,102 as per the given fractions.

GCF of 247,690,102 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 690,121,145

LCM of Fractions 690/247,121/690,145/102 is 2421210

5 690, 121, 145
138, 121, 29

∴ So the LCM of the given numbers is 5 x 138 x 121 x 29 = 2421210

Least Common Multiple of 690,121,145 with GCF Formula

Least Common Multiple of 690,121,145 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 690,121,145 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(690,121,145) = 1

common factors(in case of two or more numbers have common factors) = 5

GCF(690,121,145) x common factors =1 x 5 = 5

LCM(690,121,145) = ( 690 × 121 × 145 ) / 5

LCM(690,121,145) = 12106050 / 5

LCM(690,121,145) = 2421210


Lets's calculate GCF of 247,690,102

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2421210/1

Therefore the LCM of Fractions 690/247,121/690,145/102 is 2421210
