Least Common Multiple of 97/90,49/18,61/28,280/20

Given numbers are 97/90,49/18,61/28,280/20

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 97,49,61,280

Least Common Multiple of Numerators i.e. LCM of 97,49,61,280 is 11597320.

GCF of Denominators means GCF of 90,18,28,20 as per the given fractions.

GCF of 90,18,28,20 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 97,49,61,280

LCM of Fractions 97/90,49/18,61/28,280/20 is 5798660

7 97, 49, 61, 280
97, 7, 61, 40

∴ So the LCM of the given numbers is 7 x 97 x 7 x 61 x 40 = 11597320

Least Common Multiple of 97,49,61,280 with GCF Formula

Least Common Multiple of 97,49,61,280 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 97,49,61,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(97,49,61,280) = 1

common factors(in case of two or more numbers have common factors) = 7

GCF(97,49,61,280) x common factors =1 x 7 = 7

LCM(97,49,61,280) = ( 97 × 49 × 61 × 280 ) / 7

LCM(97,49,61,280) = 81181240 / 7

LCM(97,49,61,280) = 11597320


Lets's calculate GCF of 90,18,28,20

2 90, 18, 28, 20
45, 9, 14, 10

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 11597320/2

Therefore the LCM of Fractions 97/90,49/18,61/28,280/20 is 5798660
