Greatest Common Factor
We found the factors 858,813 . The biggest common factor number is the GCF number.
So the greatest common factor 858,813 is 3.
Lets's calculate LCM of 719,712
Given numbers has no common factors except 1. So, there LCM is their product i.e 511928
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/511928
Therefore, the GCF of Fractions 858/719,813/712 is 3/511928
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 719,712 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(719,712) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(719,712) x common factors =1 x 1 = 1
LCM(719,712) = ( 719 × 712 ) / 1
LCM(719,712) = 511928 / 1
LCM(719,712) = 511928
