Therefore, the GCF of Fractions 168/858,3954/315 is 6/90090
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 858,315 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(858,315) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(858,315) x common factors =3 x 1 = 3
LCM(858,315) = ( 858 × 315 ) / 3
LCM(858,315) = 270270 / 3
LCM(858,315) = 90090
