Lets's calculate LCM of 563,731
Given numbers has no common factors except 1. So, there LCM is their product i.e 411553
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/411553
Therefore, the GCF of Fractions 638/563,363/731 is 11/411553
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 563,731 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(563,731) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(563,731) x common factors =1 x 1 = 1
LCM(563,731) = ( 563 × 731 ) / 1
LCM(563,731) = 411553 / 1
LCM(563,731) = 411553
