Lets's calculate LCM of 268,709
Given numbers has no common factors except 1. So, there LCM is their product i.e 190012
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/190012
Therefore, the GCF of Fractions 644/268,4710/709 is 2/190012
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 268,709 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(268,709) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(268,709) x common factors =1 x 1 = 1
LCM(268,709) = ( 268 × 709 ) / 1
LCM(268,709) = 190012 / 1
LCM(268,709) = 190012
