Lets's calculate LCM of 988,677
Given numbers has no common factors except 1. So, there LCM is their product i.e 668876
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/668876
Therefore, the GCF of Fractions 789/988,442/677 is 1/668876
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 988,677 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(988,677) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(988,677) x common factors =1 x 1 = 1
LCM(988,677) = ( 988 × 677 ) / 1
LCM(988,677) = 668876 / 1
LCM(988,677) = 668876
