Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30482004

Therefore, the GCF of Fractions 91/19,62/84,80/71,78/269 is 1/30482004

Least Common Multiple of 19,84,71,269 with GCF Formula

Least Common Multiple of 19,84,71,269 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 19,84,71,269 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(19,84,71,269) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(19,84,71,269) x common factors =1 x 1 = 1

LCM(19,84,71,269) = ( 19 × 84 × 71 × 269 ) / 1

LCM(19,84,71,269) = 30482004 / 1

LCM(19,84,71,269) = 30482004
