Lets's calculate LCM of 521,661
Given numbers has no common factors except 1. So, there LCM is their product i.e 344381
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/344381
Therefore, the GCF of Fractions 803/521,408/661 is 1/344381
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 521,661 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(521,661) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(521,661) x common factors =1 x 1 = 1
LCM(521,661) = ( 521 × 661 ) / 1
LCM(521,661) = 344381 / 1
LCM(521,661) = 344381
