So the greatest common factor 43,28,210 is 1.

Lets's calculate LCM of 80,543,800

2 80, 543, 800
2 40, 543, 400
2 20, 543, 200
2 10, 543, 100
5 5, 543, 50
1, 543, 10

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 1 x 543 x 10 = 434400

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/434400

Therefore, the GCF of Fractions 43/80,28/543,210/800 is 1/434400

Least Common Multiple of 80,543,800 with GCF Formula

Least Common Multiple of 80,543,800 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 80,543,800 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,543,800) = 1

common factors(in case of two or more numbers have common factors) = 80

GCF(80,543,800) x common factors =1 x 80 = 80

LCM(80,543,800) = ( 80 × 543 × 800 ) / 80

LCM(80,543,800) = 34752000 / 80

LCM(80,543,800) = 434400
