So the greatest common factor 57,25,210 is 1.

Lets's calculate LCM of 140,987,235

5 140, 987, 235
7 28, 987, 47
47 4, 141, 47
4, 3, 1

∴ So the LCM of the given numbers is 5 x 7 x 47 x 4 x 3 x 1 = 19740

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19740

Therefore, the GCF of Fractions 57/140,25/987,210/235 is 1/19740

Least Common Multiple of 140,987,235 with GCF Formula

Least Common Multiple of 140,987,235 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 140,987,235 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(140,987,235) = 1

common factors(in case of two or more numbers have common factors) = 1645

GCF(140,987,235) x common factors =1 x 1645 = 1645

LCM(140,987,235) = ( 140 × 987 × 235 ) / 1645

LCM(140,987,235) = 32472300 / 1645

LCM(140,987,235) = 19740
