Lets's calculate LCM of 806,634
2 | 806, 634 |
403, 317 |
∴ So the LCM of the given numbers is 2 x 403 x 317 = 255502
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 69/255502
Therefore, the GCF of Fractions 759/806,690/634 is 69/255502
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 806,634 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(806,634) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(806,634) x common factors =2 x 1 = 2
LCM(806,634) = ( 806 × 634 ) / 2
LCM(806,634) = 511004 / 2
LCM(806,634) = 255502
