Lets's calculate LCM of 639,197
Given numbers has no common factors except 1. So, there LCM is their product i.e 125883
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/125883
Therefore, the GCF of Fractions 553/639,396/197 is 1/125883
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 639,197 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(639,197) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(639,197) x common factors =1 x 1 = 1
LCM(639,197) = ( 639 × 197 ) / 1
LCM(639,197) = 125883 / 1
LCM(639,197) = 125883
