Greatest Common Factor
We found the factors 579,749 . The biggest common factor number is the GCF number.
So the greatest common factor 579,749 is 1.
Lets's calculate LCM of 770,839
Given numbers has no common factors except 1. So, there LCM is their product i.e 646030
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/646030
Therefore, the GCF of Fractions 579/770,749/839 is 1/646030
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 770,839 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(770,839) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(770,839) x common factors =1 x 1 = 1
LCM(770,839) = ( 770 × 839 ) / 1
LCM(770,839) = 646030 / 1
LCM(770,839) = 646030
