Least Common Multiple of 74/42,77/538,730/139

Given numbers are 74/42,77/538,730/139

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 74,77,730

Least Common Multiple of Numerators i.e. LCM of 74,77,730 is 2079770.

GCF of Denominators means GCF of 42,538,139 as per the given fractions.

GCF of 42,538,139 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 74,77,730

LCM of Fractions 74/42,77/538,730/139 is 2079770

2 74, 77, 730
37, 77, 365

∴ So the LCM of the given numbers is 2 x 37 x 77 x 365 = 2079770

Least Common Multiple of 74,77,730 with GCF Formula

Least Common Multiple of 74,77,730 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 74,77,730 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(74,77,730) = 1

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

GCF(74,77,730) x common factors =1 x 2 = 2

LCM(74,77,730) = ( 74 × 77 × 730 ) / 2

LCM(74,77,730) = 4159540 / 2

LCM(74,77,730) = 2079770


Lets's calculate GCF of 42,538,139

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2079770/1

Therefore the LCM of Fractions 74/42,77/538,730/139 is 2079770
