Lets's calculate LCM of 81,720
| 3 | 81, 720 |
| 3 | 27, 240 |
| 9, 80 |
∴ So the LCM of the given numbers is 3 x 3 x 9 x 80 = 6480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6480
Therefore, the GCF of Fractions 103/81,153/720 is 1/6480
Least Common Multiple of 81,720 with GCF Formula
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 81,720 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,720) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(81,720) x common factors =9 x 1 = 9
LCM(81,720) = ( 81 × 720 ) / 9
LCM(81,720) = 58320 / 9
LCM(81,720) = 6480
