Greatest Common Factor
We found the factors 34,688,681 . The biggest common factor number is the GCF number.
So the greatest common factor 34,688,681 is 1.
Lets's calculate LCM of 31,34,367
Given numbers has no common factors except 1. So, there LCM is their product i.e 386818
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/386818
Therefore, the GCF of Fractions 34/31,688/34,681/367 is 1/386818
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 31,34,367 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,34,367) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,34,367) x common factors =1 x 1 = 1
LCM(31,34,367) = ( 31 × 34 × 367 ) / 1
LCM(31,34,367) = 386818 / 1
LCM(31,34,367) = 386818
