Lets's calculate LCM of 20,81,52

2 20, 81, 52
2 10, 81, 26
5, 81, 13

∴ So the LCM of the given numbers is 2 x 2 x 5 x 81 x 13 = 21060

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21060

Therefore, the GCF of Fractions 985/20,132/81,257/52 is 1/21060

Least Common Multiple of 20,81,52 with GCF Formula

Least Common Multiple of 20,81,52 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 20,81,52 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,81,52) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(20,81,52) x common factors =1 x 4 = 4

LCM(20,81,52) = ( 20 × 81 × 52 ) / 4

LCM(20,81,52) = 84240 / 4

LCM(20,81,52) = 21060
