Lets's calculate LCM of 196,415
Given numbers has no common factors except 1. So, there LCM is their product i.e 81340
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/81340
Therefore, the GCF of Fractions 664/196,428/415 is 4/81340
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 196,415 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(196,415) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(196,415) x common factors =1 x 1 = 1
LCM(196,415) = ( 196 × 415 ) / 1
LCM(196,415) = 81340 / 1
LCM(196,415) = 81340
