Least Common Multiple of 98/22,49/71,70/45,84/18

Given numbers are 98/22,49/71,70/45,84/18

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 98,49,70,84

Least Common Multiple of Numerators i.e. LCM of 98,49,70,84 is 2940.

GCF of Denominators means GCF of 22,71,45,18 as per the given fractions.

GCF of 22,71,45,18 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 98,49,70,84

LCM of Fractions 98/22,49/71,70/45,84/18 is 2940

2 98, 49, 70, 84
7 49, 49, 35, 42
7 7, 7, 5, 6
1, 1, 5, 6

∴ So the LCM of the given numbers is 2 x 7 x 7 x 1 x 1 x 5 x 6 = 2940

Least Common Multiple of 98,49,70,84 with GCF Formula

Least Common Multiple of 98,49,70,84 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 98,49,70,84 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(98,49,70,84) = 7

common factors(in case of two or more numbers have common factors) = 1372

GCF(98,49,70,84) x common factors =7 x 1372 = 9604

LCM(98,49,70,84) = ( 98 × 49 × 70 × 84 ) / 9604

LCM(98,49,70,84) = 28235760 / 9604

LCM(98,49,70,84) = 2940


Lets's calculate GCF of 22,71,45,18

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2940/1

Therefore the LCM of Fractions 98/22,49/71,70/45,84/18 is 2940
