Least Common Multiple of 880/812,1240/7642

Given numbers are 880/812,1240/7642

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 880,1240

Least Common Multiple of Numerators i.e. LCM of 880,1240 is 27280.

GCF of Denominators means GCF of 812,7642 as per the given fractions.

GCF of 812,7642 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 880,1240

LCM of Fractions 880/812,1240/7642 is 13640

2 880, 1240
2 440, 620
2 220, 310
5 110, 155
22, 31

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 22 x 31 = 27280

Least Common Multiple of 880,1240 with GCF Formula

Least Common Multiple of 880,1240 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 880,1240 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(880,1240) = 40

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

GCF(880,1240) x common factors =40 x 1 = 40

LCM(880,1240) = ( 880 × 1240 ) / 40

LCM(880,1240) = 1091200 / 40

LCM(880,1240) = 27280


Lets's calculate GCF of 812,7642

2 812, 7642
406, 3821

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 27280/2

Therefore the LCM of Fractions 880/812,1240/7642 is 13640
