So the greatest common factor 13,798,279 is 1.
Lets's calculate LCM of 89,71,877
Given numbers has no common factors except 1. So, there LCM is their product i.e 5541763
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5541763
Therefore, the GCF of Fractions 13/89,798/71,279/877 is 1/5541763
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 89,71,877 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,71,877) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,71,877) x common factors =1 x 1 = 1
LCM(89,71,877) = ( 89 × 71 × 877 ) / 1
LCM(89,71,877) = 5541763 / 1
LCM(89,71,877) = 5541763
