So the greatest common factor 285,196,221 is 1.

Lets's calculate LCM of 88,40,543

2 88, 40, 543
2 44, 20, 543
2 22, 10, 543
11, 5, 543

∴ So the LCM of the given numbers is 2 x 2 x 2 x 11 x 5 x 543 = 238920

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/238920

Therefore, the GCF of Fractions 285/88,196/40,221/543 is 1/238920

Least Common Multiple of 88,40,543 with GCF Formula

Least Common Multiple of 88,40,543 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 88,40,543 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(88,40,543) = 1

common factors(in case of two or more numbers have common factors) = 8

GCF(88,40,543) x common factors =1 x 8 = 8

LCM(88,40,543) = ( 88 × 40 × 543 ) / 8

LCM(88,40,543) = 1911360 / 8

LCM(88,40,543) = 238920
