Greatest Common Factor
We found the factors 388,2048 . The biggest common factor number is the GCF number.
So the greatest common factor 388,2048 is 4.
Lets's calculate LCM of 383,578
Given numbers has no common factors except 1. So, there LCM is their product i.e 221374
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/221374
Therefore, the GCF of Fractions 388/383,2048/578 is 4/221374
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 383,578 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(383,578) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(383,578) x common factors =1 x 1 = 1
LCM(383,578) = ( 383 × 578 ) / 1
LCM(383,578) = 221374 / 1
LCM(383,578) = 221374
Here are some samples of GCF of Fractions calculations.
