LCM of:

Least Common Multiple of 8/45,5/85,69/80,55/130

Given numbers are 8/45,5/85,69/80,55/130

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 8,5,69,55

Least Common Multiple of Numerators i.e. LCM of 8,5,69,55 is 30360.

GCF of Denominators means GCF of 45,85,80,130 as per the given fractions.

GCF of 45,85,80,130 is 5 as it is the largest common factor for these numbers.

Lets's calculate LCM of 8,5,69,55

LCM of Fractions 8/45,5/85,69/80,55/130 is 6072

5 8, 5, 69, 55
8, 1, 69, 11

∴ So the LCM of the given numbers is 5 x 8 x 1 x 69 x 11 = 30360

Least Common Multiple of 8,5,69,55 with GCF Formula

Least Common Multiple of 8,5,69,55 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 8,5,69,55 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(8,5,69,55) = 1

common factors(in case of two or more numbers have common factors) = 5

GCF(8,5,69,55) x common factors =1 x 5 = 5

LCM(8,5,69,55) = ( 8 × 5 × 69 × 55 ) / 5

LCM(8,5,69,55) = 151800 / 5

LCM(8,5,69,55) = 30360


Lets's calculate GCF of 45,85,80,130

5 45, 85, 80, 130
9, 17, 16, 26

∴ So the GCF of the given numbers is 5 = 5

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 30360/5

Therefore the LCM of Fractions 8/45,5/85,69/80,55/130 is 6072
