Greatest Common Factor
We found the factors 7870,8690 . The biggest common factor number is the GCF number.
So the greatest common factor 7870,8690 is 10.
Lets's calculate LCM of 806,849
Given numbers has no common factors except 1. So, there LCM is their product i.e 684294
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/684294
Therefore, the GCF of Fractions 7870/806,8690/849 is 10/684294
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 806,849 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(806,849) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(806,849) x common factors =1 x 1 = 1
LCM(806,849) = ( 806 × 849 ) / 1
LCM(806,849) = 684294 / 1
LCM(806,849) = 684294
