Lets's calculate LCM of 80,20,681

2 80, 20, 681
2 40, 10, 681
5 20, 5, 681
4, 1, 681

∴ So the LCM of the given numbers is 2 x 2 x 5 x 4 x 1 x 681 = 54480

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/54480

Therefore, the GCF of Fractions 27/80,38/20,904/681 is 1/54480

Least Common Multiple of 80,20,681 with GCF Formula

Least Common Multiple of 80,20,681 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 80,20,681 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,20,681) = 1

common factors(in case of two or more numbers have common factors) = 20

GCF(80,20,681) x common factors =1 x 20 = 20

LCM(80,20,681) = ( 80 × 20 × 681 ) / 20

LCM(80,20,681) = 1089600 / 20

LCM(80,20,681) = 54480
