Lets's calculate LCM of 91,12,38,884

2 91, 12, 38, 884
2 91, 6, 19, 442
13 91, 3, 19, 221
7, 3, 19, 17

∴ So the LCM of the given numbers is 2 x 2 x 13 x 7 x 3 x 19 x 17 = 352716

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/352716

Therefore, the GCF of Fractions 83/91,89/12,38/38,30/884 is 1/352716

Least Common Multiple of 91,12,38,884 with GCF Formula

Least Common Multiple of 91,12,38,884 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 91,12,38,884 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(91,12,38,884) = 1

common factors(in case of two or more numbers have common factors) = 104

GCF(91,12,38,884) x common factors =1 x 104 = 104

LCM(91,12,38,884) = ( 91 × 12 × 38 × 884 ) / 104

LCM(91,12,38,884) = 36682464 / 104

LCM(91,12,38,884) = 352716
