Lets's calculate LCM of 677,877,396
Given numbers has no common factors except 1. So, there LCM is their product i.e 235116684
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/235116684
Therefore, the GCF of Fractions 77/677,572/877,639/396 is 1/235116684
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 677,877,396 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(677,877,396) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(677,877,396) x common factors =1 x 1 = 1
LCM(677,877,396) = ( 677 × 877 × 396 ) / 1
LCM(677,877,396) = 235116684 / 1
LCM(677,877,396) = 235116684
