LCM of:

Least Common Multiple of 74/84,71/67,31/70,68/647

Given numbers are 74/84,71/67,31/70,68/647

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 74,71,31,68

Least Common Multiple of Numerators i.e. LCM of 74,71,31,68 is 5537716.

GCF of Denominators means GCF of 84,67,70,647 as per the given fractions.

GCF of 84,67,70,647 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 74,71,31,68

LCM of Fractions 74/84,71/67,31/70,68/647 is 5537716

2 74, 71, 31, 68
37, 71, 31, 34

∴ So the LCM of the given numbers is 2 x 37 x 71 x 31 x 34 = 5537716

Least Common Multiple of 74,71,31,68 with GCF Formula

Least Common Multiple of 74,71,31,68 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 74,71,31,68 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(74,71,31,68) = 1

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

GCF(74,71,31,68) x common factors =1 x 2 = 2

LCM(74,71,31,68) = ( 74 × 71 × 31 × 68 ) / 2

LCM(74,71,31,68) = 11075432 / 2

LCM(74,71,31,68) = 5537716


Lets's calculate GCF of 84,67,70,647

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 5537716/1

Therefore the LCM of Fractions 74/84,71/67,31/70,68/647 is 5537716
