Least Common Multiple of 638/89,980/7240

Given numbers are 638/89,980/7240

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 638,980

Least Common Multiple of Numerators i.e. LCM of 638,980 is 312620.

GCF of Denominators means GCF of 89,7240 as per the given fractions.

GCF of 89,7240 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 638,980

LCM of Fractions 638/89,980/7240 is 312620

2 638, 980
319, 490

∴ So the LCM of the given numbers is 2 x 319 x 490 = 312620

Least Common Multiple of 638,980 with GCF Formula

Least Common Multiple of 638,980 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 638,980 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(638,980) = 2

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

GCF(638,980) x common factors =2 x 1 = 2

LCM(638,980) = ( 638 × 980 ) / 2

LCM(638,980) = 625240 / 2

LCM(638,980) = 312620


Lets's calculate GCF of 89,7240

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 312620/1

Therefore the LCM of Fractions 638/89,980/7240 is 312620
