We found the factors 70,5480 . The biggest common factor number is the GCF number.
So the greatest common factor 70,5480 is 10.
Lets's calculate LCM of 789,3991
Given numbers has no common factors except 1. So, there LCM is their product i.e 3148899
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/3148899
Therefore, the GCF of Fractions 70/789,5480/3991 is 10/3148899
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 789,3991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(789,3991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(789,3991) x common factors =1 x 1 = 1
LCM(789,3991) = ( 789 × 3991 ) / 1
LCM(789,3991) = 3148899 / 1
LCM(789,3991) = 3148899
