So the greatest common factor 69,71,43 is 1.

Lets's calculate LCM of 82,84,392

2 82, 84, 392
2 41, 42, 196
7 41, 21, 98
41, 3, 14

∴ So the LCM of the given numbers is 2 x 2 x 7 x 41 x 3 x 14 = 48216

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/48216

Therefore, the GCF of Fractions 69/82,71/84,43/392 is 1/48216

Least Common Multiple of 82,84,392 with GCF Formula

Least Common Multiple of 82,84,392 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 82,84,392 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(82,84,392) = 2

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

GCF(82,84,392) x common factors =2 x 28 = 56

LCM(82,84,392) = ( 82 × 84 × 392 ) / 56

LCM(82,84,392) = 2700096 / 56

LCM(82,84,392) = 48216
