So the greatest common factor 429,870 is 3.
Lets's calculate LCM of 602,799
Given numbers has no common factors except 1. So, there LCM is their product i.e 480998
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/480998
Therefore, the GCF of Fractions 429/602,870/799 is 3/480998
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 602,799 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(602,799) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(602,799) x common factors =1 x 1 = 1
LCM(602,799) = ( 602 × 799 ) / 1
LCM(602,799) = 480998 / 1
LCM(602,799) = 480998
