So the greatest common factor 47,82,18,84 is 1.

Lets's calculate LCM of 91,42,40,868

2 91, 42, 40, 868
2 91, 21, 20, 434
7 91, 21, 10, 217
13, 3, 10, 31

∴ So the LCM of the given numbers is 2 x 2 x 7 x 13 x 3 x 10 x 31 = 338520

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/338520

Least Common Multiple of 91,42,40,868 with GCF Formula

Least Common Multiple of 91,42,40,868 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 91,42,40,868 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(91,42,40,868) = 1

common factors(in case of two or more numbers have common factors) = 392

GCF(91,42,40,868) x common factors =1 x 392 = 392

LCM(91,42,40,868) = ( 91 × 42 × 40 × 868 ) / 392

LCM(91,42,40,868) = 132699840 / 392

LCM(91,42,40,868) = 338520
