Lets's calculate LCM of 308,659
Given numbers has no common factors except 1. So, there LCM is their product i.e 202972
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/202972
Therefore, the GCF of Fractions 728/308,432/659 is 8/202972
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 308,659 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(308,659) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(308,659) x common factors =1 x 1 = 1
LCM(308,659) = ( 308 × 659 ) / 1
LCM(308,659) = 202972 / 1
LCM(308,659) = 202972
