Lets's calculate LCM of 688,595,643
Given numbers has no common factors except 1. So, there LCM is their product i.e 263218480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/263218480
Therefore, the GCF of Fractions 83/688,23/595,561/643 is 1/263218480
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 688,595,643 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(688,595,643) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(688,595,643) x common factors =1 x 1 = 1
LCM(688,595,643) = ( 688 × 595 × 643 ) / 1
LCM(688,595,643) = 263218480 / 1
LCM(688,595,643) = 263218480
