So the greatest common factor 71,424,140 is 1.
Lets's calculate LCM of 279,913,149
Given numbers has no common factors except 1. So, there LCM is their product i.e 37954323
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/37954323
Therefore, the GCF of Fractions 71/279,424/913,140/149 is 1/37954323
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 279,913,149 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(279,913,149) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(279,913,149) x common factors =1 x 1 = 1
LCM(279,913,149) = ( 279 × 913 × 149 ) / 1
LCM(279,913,149) = 37954323 / 1
LCM(279,913,149) = 37954323
