Lets's calculate LCM of 419,829,247
Given numbers has no common factors except 1. So, there LCM is their product i.e 85795697
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/85795697
Therefore, the GCF of Fractions 71/419,42/829,934/247 is 1/85795697
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 419,829,247 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(419,829,247) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(419,829,247) x common factors =1 x 1 = 1
LCM(419,829,247) = ( 419 × 829 × 247 ) / 1
LCM(419,829,247) = 85795697 / 1
LCM(419,829,247) = 85795697
