Lets's calculate LCM of 905,759
Given numbers has no common factors except 1. So, there LCM is their product i.e 686895
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/686895
Therefore, the GCF of Fractions 392/905,355/759 is 1/686895
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 905,759 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(905,759) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(905,759) x common factors =1 x 1 = 1
LCM(905,759) = ( 905 × 759 ) / 1
LCM(905,759) = 686895 / 1
LCM(905,759) = 686895
