Least Common Multiple of 485/80,1445/680

Given numbers are 485/80,1445/680

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 485,1445

Least Common Multiple of Numerators i.e. LCM of 485,1445 is 140165.

GCF of Denominators means GCF of 80,680 as per the given fractions.

GCF of 80,680 is 40 as it is the largest common factor for these numbers.

Lets's calculate LCM of 485,1445

LCM of Fractions 485/80,1445/680 is 140165/40

5 485, 1445
97, 289

∴ So the LCM of the given numbers is 5 x 97 x 289 = 140165

Least Common Multiple of 485,1445 with GCF Formula

Least Common Multiple of 485,1445 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 485,1445 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(485,1445) = 5

common factors(in case of two or more numbers have common factors) = 1

GCF(485,1445) x common factors =5 x 1 = 5

LCM(485,1445) = ( 485 × 1445 ) / 5

LCM(485,1445) = 700825 / 5

LCM(485,1445) = 140165


Lets's calculate GCF of 80,680

2 80, 680
2 40, 340
2 20, 170
5 10, 85
2, 17

∴ So the GCF of the given numbers is 2 x 2 x 2 x 5 = 40

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 140165/40

Therefore the LCM of Fractions 485/80,1445/680 is 140165/40
