So the greatest common factor 57,399,720 is 3.
Lets's calculate LCM of 99,46,131
Given numbers has no common factors except 1. So, there LCM is their product i.e 596574
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/596574
Therefore, the GCF of Fractions 57/99,399/46,720/131 is 3/596574
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 99,46,131 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,46,131) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(99,46,131) x common factors =1 x 1 = 1
LCM(99,46,131) = ( 99 × 46 × 131 ) / 1
LCM(99,46,131) = 596574 / 1
LCM(99,46,131) = 596574
