Least Common Multiple of 77/98,38/90,85/14,51/89

Given numbers are 77/98,38/90,85/14,51/89

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 77,38,85,51

Least Common Multiple of Numerators i.e. LCM of 77,38,85,51 is 746130.

GCF of Denominators means GCF of 98,90,14,89 as per the given fractions.

GCF of 98,90,14,89 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 77,38,85,51

LCM of Fractions 77/98,38/90,85/14,51/89 is 746130

17 77, 38, 85, 51
77, 38, 5, 3

∴ So the LCM of the given numbers is 17 x 77 x 38 x 5 x 3 = 746130

Least Common Multiple of 77,38,85,51 with GCF Formula

Least Common Multiple of 77,38,85,51 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 77,38,85,51 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,38,85,51) = 1

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

GCF(77,38,85,51) x common factors =1 x 17 = 17

LCM(77,38,85,51) = ( 77 × 38 × 85 × 51 ) / 17

LCM(77,38,85,51) = 12684210 / 17

LCM(77,38,85,51) = 746130


Lets's calculate GCF of 98,90,14,89

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 746130/1

Therefore the LCM of Fractions 77/98,38/90,85/14,51/89 is 746130
