So the greatest common factor 2085,2254 is 1.
Lets's calculate LCM of 810,638
2 | 810, 638 |
405, 319 |
∴ So the LCM of the given numbers is 2 x 405 x 319 = 258390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/258390
Therefore, the GCF of Fractions 2085/810,2254/638 is 1/258390
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 810,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(810,638) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(810,638) x common factors =2 x 1 = 2
LCM(810,638) = ( 810 × 638 ) / 2
LCM(810,638) = 516780 / 2
LCM(810,638) = 258390
