So the greatest common factor 91,12,10,74 is 1.

Lets's calculate LCM of 82,19,45,404

2 82, 19, 45, 404
41, 19, 45, 202

∴ So the LCM of the given numbers is 2 x 41 x 19 x 45 x 202 = 14162220

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/14162220

Therefore, the GCF of Fractions 91/82,12/19,10/45,74/404 is 1/14162220

Least Common Multiple of 82,19,45,404 with GCF Formula

Least Common Multiple of 82,19,45,404 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 82,19,45,404 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(82,19,45,404) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(82,19,45,404) x common factors =1 x 2 = 2

LCM(82,19,45,404) = ( 82 × 19 × 45 × 404 ) / 2

LCM(82,19,45,404) = 28324440 / 2

LCM(82,19,45,404) = 14162220
