So the greatest common factor 86,30,358 is 2.
Lets's calculate LCM of 139,581,659
Given numbers has no common factors except 1. So, there LCM is their product i.e 53220181
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/53220181
Therefore, the GCF of Fractions 86/139,30/581,358/659 is 2/53220181
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 139,581,659 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(139,581,659) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(139,581,659) x common factors =1 x 1 = 1
LCM(139,581,659) = ( 139 × 581 × 659 ) / 1
LCM(139,581,659) = 53220181 / 1
LCM(139,581,659) = 53220181
