Greatest Common Factor
We found the factors 309,998 . The biggest common factor number is the GCF number.
So the greatest common factor 309,998 is 1.
Lets's calculate LCM of 945,761
Given numbers has no common factors except 1. So, there LCM is their product i.e 719145
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/719145
Therefore, the GCF of Fractions 309/945,998/761 is 1/719145
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 945,761 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(945,761) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(945,761) x common factors =1 x 1 = 1
LCM(945,761) = ( 945 × 761 ) / 1
LCM(945,761) = 719145 / 1
LCM(945,761) = 719145
