So the greatest common factor 1644,2620 is 4.
Lets's calculate LCM of 955,811
Given numbers has no common factors except 1. So, there LCM is their product i.e 774505
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/774505
Therefore, the GCF of Fractions 1644/955,2620/811 is 4/774505
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 955,811 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(955,811) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(955,811) x common factors =1 x 1 = 1
LCM(955,811) = ( 955 × 811 ) / 1
LCM(955,811) = 774505 / 1
LCM(955,811) = 774505
Here are some samples of GCF of Fractions calculations.
