Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/27930
Therefore, the GCF of Fractions 794/798,676/490 is 2/27930
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 798,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(798,490) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(798,490) x common factors =14 x 1 = 14
LCM(798,490) = ( 798 × 490 ) / 14
LCM(798,490) = 391020 / 14
LCM(798,490) = 27930
