So the greatest common factor 753,663 is 3.
Lets's calculate LCM of 905,917
Given numbers has no common factors except 1. So, there LCM is their product i.e 829885
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/829885
Therefore, the GCF of Fractions 753/905,663/917 is 3/829885
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 905,917 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(905,917) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(905,917) x common factors =1 x 1 = 1
LCM(905,917) = ( 905 × 917 ) / 1
LCM(905,917) = 829885 / 1
LCM(905,917) = 829885
