Least Common Multiple of 39/18,640/94,178/138

Given numbers are 39/18,640/94,178/138

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 39,640,178

Least Common Multiple of Numerators i.e. LCM of 39,640,178 is 2221440.

GCF of Denominators means GCF of 18,94,138 as per the given fractions.

GCF of 18,94,138 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 39,640,178

LCM of Fractions 39/18,640/94,178/138 is 1110720

2 39, 640, 178
39, 320, 89

∴ So the LCM of the given numbers is 2 x 39 x 320 x 89 = 2221440

Least Common Multiple of 39,640,178 with GCF Formula

Least Common Multiple of 39,640,178 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 39,640,178 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(39,640,178) = 1

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

GCF(39,640,178) x common factors =1 x 2 = 2

LCM(39,640,178) = ( 39 × 640 × 178 ) / 2

LCM(39,640,178) = 4442880 / 2

LCM(39,640,178) = 2221440


Lets's calculate GCF of 18,94,138

2 18, 94, 138
9, 47, 69

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2221440/2

Therefore the LCM of Fractions 39/18,640/94,178/138 is 1110720
