Lets's calculate LCM of 757,9894
Given numbers has no common factors except 1. So, there LCM is their product i.e 7489758
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 19/7489758
Therefore, the GCF of Fractions 399/757,8398/9894 is 19/7489758
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 757,9894 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(757,9894) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(757,9894) x common factors =1 x 1 = 1
LCM(757,9894) = ( 757 × 9894 ) / 1
LCM(757,9894) = 7489758 / 1
LCM(757,9894) = 7489758
