We found the factors 80,900,180 . The biggest common factor number is the GCF number.
So the greatest common factor 80,900,180 is 20.
Lets's calculate LCM of 57,31,368
Given numbers has no common factors except 1. So, there LCM is their product i.e 650256
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/650256
Therefore, the GCF of Fractions 80/57,900/31,180/368 is 20/650256
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 57,31,368 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,31,368) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(57,31,368) x common factors =1 x 1 = 1
LCM(57,31,368) = ( 57 × 31 × 368 ) / 1
LCM(57,31,368) = 650256 / 1
LCM(57,31,368) = 650256
