So the greatest common factor 420,812 is 28.
Lets's calculate LCM of 94,683
Given numbers has no common factors except 1. So, there LCM is their product i.e 64202
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 28/64202
Therefore, the GCF of Fractions 420/94,812/683 is 28/64202
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 94,683 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(94,683) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(94,683) x common factors =1 x 1 = 1
LCM(94,683) = ( 94 × 683 ) / 1
LCM(94,683) = 64202 / 1
LCM(94,683) = 64202
