Lets's calculate LCM of 971,671,530
Given numbers has no common factors except 1. So, there LCM is their product i.e 345316730
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/345316730
Therefore, the GCF of Fractions 79/971,42/671,688/530 is 1/345316730
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 971,671,530 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(971,671,530) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(971,671,530) x common factors =1 x 1 = 1
LCM(971,671,530) = ( 971 × 671 × 530 ) / 1
LCM(971,671,530) = 345316730 / 1
LCM(971,671,530) = 345316730
