Now, list down the factors of 856
:1,2,4,8,107,214,428,856
Now, list down the factors of 7891
:1,13,607,7891
Greatest Common Factor
We found the factors 856,7891 . The biggest common factor number is the GCF number.
So the greatest common factor 856,7891 is 1.
Lets's calculate LCM of 510,809
Given numbers has no common factors except 1. So, there LCM is their product i.e 412590
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/412590
Therefore, the GCF of Fractions 856/510,7891/809 is 1/412590
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 510,809 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(510,809) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(510,809) x common factors =1 x 1 = 1
LCM(510,809) = ( 510 × 809 ) / 1
LCM(510,809) = 412590 / 1
LCM(510,809) = 412590
