Greatest Common Factor
We found the factors 509,741,400 . The biggest common factor number is the GCF number.
So the greatest common factor 509,741,400 is 1.
Lets's calculate LCM of 81,85,691
Given numbers has no common factors except 1. So, there LCM is their product i.e 4757535
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4757535
Therefore, the GCF of Fractions 509/81,741/85,400/691 is 1/4757535
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 81,85,691 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,85,691) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,85,691) x common factors =1 x 1 = 1
LCM(81,85,691) = ( 81 × 85 × 691 ) / 1
LCM(81,85,691) = 4757535 / 1
LCM(81,85,691) = 4757535
