Lets's calculate LCM of 75,799
Given numbers has no common factors except 1. So, there LCM is their product i.e 59925
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/59925
Therefore, the GCF of Fractions 690/75,868/799 is 2/59925
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 75,799 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(75,799) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(75,799) x common factors =1 x 1 = 1
LCM(75,799) = ( 75 × 799 ) / 1
LCM(75,799) = 59925 / 1
LCM(75,799) = 59925
