Lets's calculate LCM of 718,885
Given numbers has no common factors except 1. So, there LCM is their product i.e 635430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 78/635430
Therefore, the GCF of Fractions 624/718,858/885 is 78/635430
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 718,885 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(718,885) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(718,885) x common factors =1 x 1 = 1
LCM(718,885) = ( 718 × 885 ) / 1
LCM(718,885) = 635430 / 1
LCM(718,885) = 635430
