So the greatest common factor 30,28,578 is 2.
Lets's calculate LCM of 713,311,693
Given numbers has no common factors except 1. So, there LCM is their product i.e 153667899
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/153667899
Therefore, the GCF of Fractions 30/713,28/311,578/693 is 2/153667899
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 713,311,693 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(713,311,693) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(713,311,693) x common factors =1 x 1 = 1
LCM(713,311,693) = ( 713 × 311 × 693 ) / 1
LCM(713,311,693) = 153667899 / 1
LCM(713,311,693) = 153667899
