Lets's calculate LCM of 857,207,470
Given numbers has no common factors except 1. So, there LCM is their product i.e 83377530
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/83377530
Therefore, the GCF of Fractions 455/857,493/207,945/470 is 1/83377530
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 857,207,470 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(857,207,470) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(857,207,470) x common factors =1 x 1 = 1
LCM(857,207,470) = ( 857 × 207 × 470 ) / 1
LCM(857,207,470) = 83377530 / 1
LCM(857,207,470) = 83377530
