Greatest Common Factor
We found the factors 20,410,602 . The biggest common factor number is the GCF number.
So the greatest common factor 20,410,602 is 2.
Lets's calculate LCM of 71,55,494
Given numbers has no common factors except 1. So, there LCM is their product i.e 1929070
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1929070
Therefore, the GCF of Fractions 20/71,410/55,602/494 is 2/1929070
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 71,55,494 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,55,494) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(71,55,494) x common factors =1 x 1 = 1
LCM(71,55,494) = ( 71 × 55 × 494 ) / 1
LCM(71,55,494) = 1929070 / 1
LCM(71,55,494) = 1929070
