Lets's calculate LCM of 217,681
Given numbers has no common factors except 1. So, there LCM is their product i.e 147777
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/147777
Therefore, the GCF of Fractions 806/217,493/681 is 1/147777
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 217,681 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(217,681) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(217,681) x common factors =1 x 1 = 1
LCM(217,681) = ( 217 × 681 ) / 1
LCM(217,681) = 147777 / 1
LCM(217,681) = 147777
