Least Common Multiple of 641/78,816/62,425/820

Given numbers are 641/78,816/62,425/820

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 641,816,425

Least Common Multiple of Numerators i.e. LCM of 641,816,425 is 13076400.

GCF of Denominators means GCF of 78,62,820 as per the given fractions.

GCF of 78,62,820 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 641,816,425

LCM of Fractions 641/78,816/62,425/820 is 6538200

17 641, 816, 425
641, 48, 25

∴ So the LCM of the given numbers is 17 x 641 x 48 x 25 = 13076400

Least Common Multiple of 641,816,425 with GCF Formula

Least Common Multiple of 641,816,425 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 641,816,425 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(641,816,425) = 1

common factors(in case of two or more numbers have common factors) = 17

GCF(641,816,425) x common factors =1 x 17 = 17

LCM(641,816,425) = ( 641 × 816 × 425 ) / 17

LCM(641,816,425) = 222298800 / 17

LCM(641,816,425) = 13076400


Lets's calculate GCF of 78,62,820

2 78, 62, 820
39, 31, 410

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 13076400/2

Therefore the LCM of Fractions 641/78,816/62,425/820 is 6538200
