So the greatest common factor 640,366 is 2.
Lets's calculate LCM of 556,985
Given numbers has no common factors except 1. So, there LCM is their product i.e 547660
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/547660
Therefore, the GCF of Fractions 640/556,366/985 is 2/547660
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 556,985 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(556,985) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(556,985) x common factors =1 x 1 = 1
LCM(556,985) = ( 556 × 985 ) / 1
LCM(556,985) = 547660 / 1
LCM(556,985) = 547660
