So the greatest common factor 81,958,500 is 1.
Lets's calculate LCM of 67,23,870
Given numbers has no common factors except 1. So, there LCM is their product i.e 1340670
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1340670
Therefore, the GCF of Fractions 81/67,958/23,500/870 is 1/1340670
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 67,23,870 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,23,870) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(67,23,870) x common factors =1 x 1 = 1
LCM(67,23,870) = ( 67 × 23 × 870 ) / 1
LCM(67,23,870) = 1340670 / 1
LCM(67,23,870) = 1340670
