Lets's calculate LCM of 97,43,447
Given numbers has no common factors except 1. So, there LCM is their product i.e 1864437
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/1864437
Therefore, the GCF of Fractions 90/97,936/43,324/447 is 18/1864437
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 97,43,447 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(97,43,447) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(97,43,447) x common factors =1 x 1 = 1
LCM(97,43,447) = ( 97 × 43 × 447 ) / 1
LCM(97,43,447) = 1864437 / 1
LCM(97,43,447) = 1864437
