So the greatest common factor 678,728 is 2.
Lets's calculate LCM of 554,631
Given numbers has no common factors except 1. So, there LCM is their product i.e 349574
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/349574
Therefore, the GCF of Fractions 678/554,728/631 is 2/349574
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 554,631 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(554,631) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(554,631) x common factors =1 x 1 = 1
LCM(554,631) = ( 554 × 631 ) / 1
LCM(554,631) = 349574 / 1
LCM(554,631) = 349574
