So the greatest common factor 544,1989 is 17.
Lets's calculate LCM of 457,767
Given numbers has no common factors except 1. So, there LCM is their product i.e 350519
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/350519
Therefore, the GCF of Fractions 544/457,1989/767 is 17/350519
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 457,767 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(457,767) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(457,767) x common factors =1 x 1 = 1
LCM(457,767) = ( 457 × 767 ) / 1
LCM(457,767) = 350519 / 1
LCM(457,767) = 350519
