Greatest Common Factor
We found the factors 245,7791 . The biggest common factor number is the GCF number.
So the greatest common factor 245,7791 is 49.
Lets's calculate LCM of 86,853
Given numbers has no common factors except 1. So, there LCM is their product i.e 73358
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 49/73358
Therefore, the GCF of Fractions 245/86,7791/853 is 49/73358
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 86,853 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,853) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(86,853) x common factors =1 x 1 = 1
LCM(86,853) = ( 86 × 853 ) / 1
LCM(86,853) = 73358 / 1
LCM(86,853) = 73358
