So the greatest common factor 858,407,416 is 1.

Lets's calculate LCM of 21,70,855

3 21, 70, 855
5 7, 70, 285
7 7, 14, 57
1, 2, 57

∴ So the LCM of the given numbers is 3 x 5 x 7 x 1 x 2 x 57 = 11970

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11970

Therefore, the GCF of Fractions 858/21,407/70,416/855 is 1/11970

Least Common Multiple of 21,70,855 with GCF Formula

Least Common Multiple of 21,70,855 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 21,70,855 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,70,855) = 1

common factors(in case of two or more numbers have common factors) = 105

GCF(21,70,855) x common factors =1 x 105 = 105

LCM(21,70,855) = ( 21 × 70 × 855 ) / 105

LCM(21,70,855) = 1256850 / 105

LCM(21,70,855) = 11970
