1,2,4,7,14,28,157,314,628,1099,2198,4396
Greatest Common Factor
We found the factors 12,4396 . The biggest common factor number is the GCF number.
So the greatest common factor 12,4396 is 4.
Lets's calculate LCM of 842,1893
Given numbers has no common factors except 1. So, there LCM is their product i.e 1593906
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/1593906
Therefore, the GCF of Fractions 12/842,4396/1893 is 4/1593906
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 842,1893 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(842,1893) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(842,1893) x common factors =1 x 1 = 1
LCM(842,1893) = ( 842 × 1893 ) / 1
LCM(842,1893) = 1593906 / 1
LCM(842,1893) = 1593906
Here are some samples of GCF of Fractions calculations.
