Lets's calculate LCM of 243,729
3 | 243, 729 |
3 | 81, 243 |
3 | 27, 81 |
3 | 9, 27 |
3 | 3, 9 |
1, 3 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 3 x 3 x 1 x 3 = 729
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/729
Therefore, the GCF of Fractions 656/243,885/729 is 1/729
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 243,729 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(243,729) = 243
common factors(in case of two or more numbers have common factors) = 1
GCF(243,729) x common factors =243 x 1 = 243
LCM(243,729) = ( 243 × 729 ) / 243
LCM(243,729) = 177147 / 243
LCM(243,729) = 729
