Lets's calculate LCM of 563,687
Given numbers has no common factors except 1. So, there LCM is their product i.e 386781
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/386781
Therefore, the GCF of Fractions 393/563,1285/687 is 1/386781
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 563,687 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(563,687) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(563,687) x common factors =1 x 1 = 1
LCM(563,687) = ( 563 × 687 ) / 1
LCM(563,687) = 386781 / 1
LCM(563,687) = 386781
