Lets's calculate LCM of 490,747
Given numbers has no common factors except 1. So, there LCM is their product i.e 366030
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/366030
Therefore, the GCF of Fractions 649/490,286/747 is 11/366030
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 490,747 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(490,747) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(490,747) x common factors =1 x 1 = 1
LCM(490,747) = ( 490 × 747 ) / 1
LCM(490,747) = 366030 / 1
LCM(490,747) = 366030
