Lets's calculate LCM of 868,811,721

LCM of Fractions 868/285,811/405,721/915 is 72506644/15

7 868, 811, 721
124, 811, 103

∴ So the LCM of the given numbers is 7 x 124 x 811 x 103 = 72506644

Least Common Multiple of 868,811,721 with GCF Formula

Least Common Multiple of 868,811,721 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 868,811,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(868,811,721) = 1

common factors(in case of two or more numbers have common factors) = 7

GCF(868,811,721) x common factors =1 x 7 = 7

LCM(868,811,721) = ( 868 × 811 × 721 ) / 7

LCM(868,811,721) = 507546508 / 7

LCM(868,811,721) = 72506644


Lets's calculate GCF of 285,405,915

3 285, 405, 915
5 95, 135, 305
19, 27, 61

∴ So the GCF of the given numbers is 3 x 5 = 15

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 72506644/15

Therefore the LCM of Fractions 868/285,811/405,721/915 is 72506644/15
