So the greatest common factor 48,38,640 is 2.
Lets's calculate LCM of 540,231,801
3 | 540, 231, 801 |
3 | 180, 77, 267 |
60, 77, 89 |
∴ So the LCM of the given numbers is 3 x 3 x 60 x 77 x 89 = 3700620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/3700620
Therefore, the GCF of Fractions 48/540,38/231,640/801 is 2/3700620
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 540,231,801 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(540,231,801) = 3
common factors(in case of two or more numbers have common factors) = 9
GCF(540,231,801) x common factors =3 x 9 = 27
LCM(540,231,801) = ( 540 × 231 × 801 ) / 27
LCM(540,231,801) = 99916740 / 27
LCM(540,231,801) = 3700620
