We found the factors 427,821 . The biggest common factor number is the GCF number.
So the greatest common factor 427,821 is 1.
Lets's calculate LCM of 682,730
2 | 682, 730 |
341, 365 |
∴ So the LCM of the given numbers is 2 x 341 x 365 = 248930
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/248930
Therefore, the GCF of Fractions 427/682,821/730 is 1/248930
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 682,730 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(682,730) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(682,730) x common factors =2 x 1 = 2
LCM(682,730) = ( 682 × 730 ) / 2
LCM(682,730) = 497860 / 2
LCM(682,730) = 248930
