Lets's calculate LCM of 239,623
Given numbers has no common factors except 1. So, there LCM is their product i.e 148897
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/148897
Therefore, the GCF of Fractions 640/239,968/623 is 8/148897
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 239,623 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(239,623) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(239,623) x common factors =1 x 1 = 1
LCM(239,623) = ( 239 × 623 ) / 1
LCM(239,623) = 148897 / 1
LCM(239,623) = 148897
