Lets's calculate LCM of 76,339,979
Given numbers has no common factors except 1. So, there LCM is their product i.e 25222956
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25222956
Therefore, the GCF of Fractions 49/76,40/339,208/979 is 1/25222956
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 76,339,979 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,339,979) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(76,339,979) x common factors =1 x 1 = 1
LCM(76,339,979) = ( 76 × 339 × 979 ) / 1
LCM(76,339,979) = 25222956 / 1
LCM(76,339,979) = 25222956
