Lets's calculate LCM of 639,397
Given numbers has no common factors except 1. So, there LCM is their product i.e 253683
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/253683
Therefore, the GCF of Fractions 644/639,871/397 is 1/253683
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 639,397 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(639,397) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(639,397) x common factors =1 x 1 = 1
LCM(639,397) = ( 639 × 397 ) / 1
LCM(639,397) = 253683 / 1
LCM(639,397) = 253683
