Greatest Common Factor
We found the factors 818,515 . The biggest common factor number is the GCF number.
So the greatest common factor 818,515 is 1.
Lets's calculate LCM of 689,135
Given numbers has no common factors except 1. So, there LCM is their product i.e 93015
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/93015
Therefore, the GCF of Fractions 818/689,515/135 is 1/93015
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 689,135 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(689,135) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(689,135) x common factors =1 x 1 = 1
LCM(689,135) = ( 689 × 135 ) / 1
LCM(689,135) = 93015 / 1
LCM(689,135) = 93015
