So the greatest common factor 753,646 is 1.
Lets's calculate LCM of 512,931
Given numbers has no common factors except 1. So, there LCM is their product i.e 476672
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/476672
Therefore, the GCF of Fractions 753/512,646/931 is 1/476672
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 512,931 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(512,931) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(512,931) x common factors =1 x 1 = 1
LCM(512,931) = ( 512 × 931 ) / 1
LCM(512,931) = 476672 / 1
LCM(512,931) = 476672
