Greatest Common Factor
We found the factors 385,840 . The biggest common factor number is the GCF number.
So the greatest common factor 385,840 is 35.
Lets's calculate LCM of 26,7756
2 | 26, 7756 |
13, 3878 |
∴ So the LCM of the given numbers is 2 x 13 x 3878 = 100828
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 35/100828
Therefore, the GCF of Fractions 385/26,840/7756 is 35/100828
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 26,7756 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(26,7756) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(26,7756) x common factors =2 x 1 = 2
LCM(26,7756) = ( 26 × 7756 ) / 2
LCM(26,7756) = 201656 / 2
LCM(26,7756) = 100828
