:1,2,13,26,31,62,403,806
Greatest Common Factor
We found the factors 931,806 . The biggest common factor number is the GCF number.
So the greatest common factor 931,806 is 1.
Lets's calculate LCM of 886,209
Given numbers has no common factors except 1. So, there LCM is their product i.e 185174
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/185174
Therefore, the GCF of Fractions 931/886,806/209 is 1/185174
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 886,209 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(886,209) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(886,209) x common factors =1 x 1 = 1
LCM(886,209) = ( 886 × 209 ) / 1
LCM(886,209) = 185174 / 1
LCM(886,209) = 185174
