Least Common Multiple of 80/56,84/39,80/31,74/655

Given numbers are 80/56,84/39,80/31,74/655

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 80,84,80,74

Least Common Multiple of Numerators i.e. LCM of 80,84,80,74 is 62160.

GCF of Denominators means GCF of 56,39,31,655 as per the given fractions.

GCF of 56,39,31,655 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 80,84,80,74

LCM of Fractions 80/56,84/39,80/31,74/655 is 62160

2 80, 84, 80, 74
2 40, 42, 40, 37
2 20, 21, 20, 37
2 10, 21, 10, 37
5 5, 21, 5, 37
1, 21, 1, 37

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 1 x 21 x 1 x 37 = 62160

Least Common Multiple of 80,84,80,74 with GCF Formula

Least Common Multiple of 80,84,80,74 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 80,84,80,74 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,84,80,74) = 2

common factors(in case of two or more numbers have common factors) = 320

GCF(80,84,80,74) x common factors =2 x 320 = 640

LCM(80,84,80,74) = ( 80 × 84 × 80 × 74 ) / 640

LCM(80,84,80,74) = 39782400 / 640

LCM(80,84,80,74) = 62160


Lets's calculate GCF of 56,39,31,655

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 62160/1

Therefore the LCM of Fractions 80/56,84/39,80/31,74/655 is 62160
