Greatest Common Factor
We found the factors 2979,1042 . The biggest common factor number is the GCF number.
So the greatest common factor 2979,1042 is 1.
Lets's calculate LCM of 391,767
Given numbers has no common factors except 1. So, there LCM is their product i.e 299897
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/299897
Therefore, the GCF of Fractions 2979/391,1042/767 is 1/299897
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 391,767 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(391,767) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(391,767) x common factors =1 x 1 = 1
LCM(391,767) = ( 391 × 767 ) / 1
LCM(391,767) = 299897 / 1
LCM(391,767) = 299897
