So the greatest common factor 356,1908 is 4.
Lets's calculate LCM of 547,643
Given numbers has no common factors except 1. So, there LCM is their product i.e 351721
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/351721
Therefore, the GCF of Fractions 356/547,1908/643 is 4/351721
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 547,643 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(547,643) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(547,643) x common factors =1 x 1 = 1
LCM(547,643) = ( 547 × 643 ) / 1
LCM(547,643) = 351721 / 1
LCM(547,643) = 351721
