LCM of:

Least Common Multiple of 42/91,94/788,455/931

Given numbers are 42/91,94/788,455/931

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 42,94,455

Least Common Multiple of Numerators i.e. LCM of 42,94,455 is 128310.

GCF of Denominators means GCF of 91,788,931 as per the given fractions.

GCF of 91,788,931 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 42,94,455

LCM of Fractions 42/91,94/788,455/931 is 128310

2 42, 94, 455
7 21, 47, 455
3, 47, 65

∴ So the LCM of the given numbers is 2 x 7 x 3 x 47 x 65 = 128310

Least Common Multiple of 42,94,455 with GCF Formula

Least Common Multiple of 42,94,455 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 42,94,455 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,94,455) = 1

common factors(in case of two or more numbers have common factors) = 14

GCF(42,94,455) x common factors =1 x 14 = 14

LCM(42,94,455) = ( 42 × 94 × 455 ) / 14

LCM(42,94,455) = 1796340 / 14

LCM(42,94,455) = 128310


Lets's calculate GCF of 91,788,931

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 128310/1

Therefore the LCM of Fractions 42/91,94/788,455/931 is 128310
