So the greatest common factor 84,55,855 is 1.
Lets's calculate LCM of 167,205,634
Given numbers has no common factors except 1. So, there LCM is their product i.e 21704990
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21704990
Therefore, the GCF of Fractions 84/167,55/205,855/634 is 1/21704990
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 167,205,634 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(167,205,634) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(167,205,634) x common factors =1 x 1 = 1
LCM(167,205,634) = ( 167 × 205 × 634 ) / 1
LCM(167,205,634) = 21704990 / 1
LCM(167,205,634) = 21704990
