So the greatest common factor 76,49,84,54 is 1.

Lets's calculate LCM of 92,56,21,811

2 92, 56, 21, 811
2 46, 28, 21, 811
7 23, 14, 21, 811
23, 2, 3, 811

∴ So the LCM of the given numbers is 2 x 2 x 7 x 23 x 2 x 3 x 811 = 3133704

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3133704

Therefore, the GCF of Fractions 76/92,49/56,84/21,54/811 is 1/3133704

Least Common Multiple of 92,56,21,811 with GCF Formula

Least Common Multiple of 92,56,21,811 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 92,56,21,811 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(92,56,21,811) = 1

common factors(in case of two or more numbers have common factors) = 28

GCF(92,56,21,811) x common factors =1 x 28 = 28

LCM(92,56,21,811) = ( 92 × 56 × 21 × 811 ) / 28

LCM(92,56,21,811) = 87743712 / 28

LCM(92,56,21,811) = 3133704
