Lets's calculate LCM of 145,972
Given numbers has no common factors except 1. So, there LCM is their product i.e 140940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 54/140940
Therefore, the GCF of Fractions 486/145,864/972 is 54/140940
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 145,972 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(145,972) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(145,972) x common factors =1 x 1 = 1
LCM(145,972) = ( 145 × 972 ) / 1
LCM(145,972) = 140940 / 1
LCM(145,972) = 140940
