So the greatest common factor 30,72,745 is 1.
Lets's calculate LCM of 921,418,619
Given numbers has no common factors except 1. So, there LCM is their product i.e 238301382
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/238301382
Therefore, the GCF of Fractions 30/921,72/418,745/619 is 1/238301382
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 921,418,619 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,418,619) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(921,418,619) x common factors =1 x 1 = 1
LCM(921,418,619) = ( 921 × 418 × 619 ) / 1
LCM(921,418,619) = 238301382 / 1
LCM(921,418,619) = 238301382
