Greatest Common Factor
We found the factors 178,689 . The biggest common factor number is the GCF number.
So the greatest common factor 178,689 is 1.
Lets's calculate LCM of 786,139
Given numbers has no common factors except 1. So, there LCM is their product i.e 109254
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/109254
Therefore, the GCF of Fractions 178/786,689/139 is 1/109254
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 786,139 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(786,139) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(786,139) x common factors =1 x 1 = 1
LCM(786,139) = ( 786 × 139 ) / 1
LCM(786,139) = 109254 / 1
LCM(786,139) = 109254
