Lets's calculate LCM of 39,26,858

2 39, 26, 858
3 39, 13, 429
13 13, 13, 143
1, 1, 11

∴ So the LCM of the given numbers is 2 x 3 x 13 x 1 x 1 x 11 = 858

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/858

Therefore, the GCF of Fractions 49/39,40/26,43/858 is 1/858

Least Common Multiple of 39,26,858 with GCF Formula

Least Common Multiple of 39,26,858 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 39,26,858 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(39,26,858) = 13

common factors(in case of two or more numbers have common factors) = 78

GCF(39,26,858) x common factors =13 x 78 = 1014

LCM(39,26,858) = ( 39 × 26 × 858 ) / 1014

LCM(39,26,858) = 870012 / 1014

LCM(39,26,858) = 858
