Greatest Common Factor
We found the factors 84,91,890 . The biggest common factor number is the GCF number.
So the greatest common factor 84,91,890 is 1.
Lets's calculate LCM of 31,872,627
Given numbers has no common factors except 1. So, there LCM is their product i.e 16949064
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/16949064
Therefore, the GCF of Fractions 84/31,91/872,890/627 is 1/16949064
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 31,872,627 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,872,627) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,872,627) x common factors =1 x 1 = 1
LCM(31,872,627) = ( 31 × 872 × 627 ) / 1
LCM(31,872,627) = 16949064 / 1
LCM(31,872,627) = 16949064
