So the greatest common factor 81,13,94,74 is 1.

Lets's calculate LCM of 66,11,91,704

2 66, 11, 91, 704
11 33, 11, 91, 352
3, 1, 91, 32

∴ So the LCM of the given numbers is 2 x 11 x 3 x 1 x 91 x 32 = 192192

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/192192

Therefore, the GCF of Fractions 81/66,13/11,94/91,74/704 is 1/192192

Least Common Multiple of 66,11,91,704 with GCF Formula

Least Common Multiple of 66,11,91,704 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 66,11,91,704 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(66,11,91,704) = 1

common factors(in case of two or more numbers have common factors) = 242

GCF(66,11,91,704) x common factors =1 x 242 = 242

LCM(66,11,91,704) = ( 66 × 11 × 91 × 704 ) / 242

LCM(66,11,91,704) = 46510464 / 242

LCM(66,11,91,704) = 192192
