Greatest Common Factor
We found the factors 122,171,709 . The biggest common factor number is the GCF number.
So the greatest common factor 122,171,709 is 1.
Lets's calculate LCM of 117,158,431
Given numbers has no common factors except 1. So, there LCM is their product i.e 7967466
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7967466
Therefore, the GCF of Fractions 122/117,171/158,709/431 is 1/7967466
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 117,158,431 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(117,158,431) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(117,158,431) x common factors =1 x 1 = 1
LCM(117,158,431) = ( 117 × 158 × 431 ) / 1
LCM(117,158,431) = 7967466 / 1
LCM(117,158,431) = 7967466
