Greatest Common Factor
We found the factors 140,451,374 . The biggest common factor number is the GCF number.
So the greatest common factor 140,451,374 is 1.
Lets's calculate LCM of 81,34,487
Given numbers has no common factors except 1. So, there LCM is their product i.e 1341198
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1341198
Therefore, the GCF of Fractions 140/81,451/34,374/487 is 1/1341198
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 81,34,487 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,34,487) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,34,487) x common factors =1 x 1 = 1
LCM(81,34,487) = ( 81 × 34 × 487 ) / 1
LCM(81,34,487) = 1341198 / 1
LCM(81,34,487) = 1341198
