GCF of Denominators means GCF of 28,970 as per the given fractions.

GCF of 28,970 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 2786,1638

LCM of Fractions 2786/28,1638/970 is 162981

2 2786, 1638
7 1393, 819
199, 117

∴ So the LCM of the given numbers is 2 x 7 x 199 x 117 = 325962

Least Common Multiple of 2786,1638 with GCF Formula

Least Common Multiple of 2786,1638 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 2786,1638 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(2786,1638) = 14

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

GCF(2786,1638) x common factors =14 x 1 = 14

LCM(2786,1638) = ( 2786 × 1638 ) / 14

LCM(2786,1638) = 4563468 / 14

LCM(2786,1638) = 325962


Lets's calculate GCF of 28,970

2 28, 970
14, 485

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 325962/2

Therefore the LCM of Fractions 2786/28,1638/970 is 162981
