So the greatest common factor 819,222 is 3.
Lets's calculate LCM of 905,686
Given numbers has no common factors except 1. So, there LCM is their product i.e 620830
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/620830
Therefore, the GCF of Fractions 819/905,222/686 is 3/620830
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 905,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(905,686) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(905,686) x common factors =1 x 1 = 1
LCM(905,686) = ( 905 × 686 ) / 1
LCM(905,686) = 620830 / 1
LCM(905,686) = 620830
