We found the factors 70,12,76 . The biggest common factor number is the GCF number.
So the greatest common factor 70,12,76 is 2.

Lets's calculate LCM of 74,42,810

2 74, 42, 810
3 37, 21, 405
37, 7, 135

∴ So the LCM of the given numbers is 2 x 3 x 37 x 7 x 135 = 209790

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/209790

Therefore, the GCF of Fractions 70/74,12/42,76/810 is 2/209790

Least Common Multiple of 74,42,810 with GCF Formula

Least Common Multiple of 74,42,810 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 74,42,810 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(74,42,810) = 2

common factors(in case of two or more numbers have common factors) = 6

GCF(74,42,810) x common factors =2 x 6 = 12

LCM(74,42,810) = ( 74 × 42 × 810 ) / 12

LCM(74,42,810) = 2517480 / 12

LCM(74,42,810) = 209790
