Greatest Common Factor
We found the factors 306,130,990 . The biggest common factor number is the GCF number.
So the greatest common factor 306,130,990 is 2.
Lets's calculate LCM of 31,70,289
Given numbers has no common factors except 1. So, there LCM is their product i.e 627130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/627130
Therefore, the GCF of Fractions 306/31,130/70,990/289 is 2/627130
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 31,70,289 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,70,289) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,70,289) x common factors =1 x 1 = 1
LCM(31,70,289) = ( 31 × 70 × 289 ) / 1
LCM(31,70,289) = 627130 / 1
LCM(31,70,289) = 627130
