So the greatest common factor 648,3993 is 3.
Lets's calculate LCM of 910,380
| 2 | 910, 380 |
| 5 | 455, 190 |
| 91, 38 |
∴ So the LCM of the given numbers is 2 x 5 x 91 x 38 = 34580
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/34580
Therefore, the GCF of Fractions 648/910,3993/380 is 3/34580
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 910,380 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(910,380) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(910,380) x common factors =10 x 1 = 10
LCM(910,380) = ( 910 × 380 ) / 10
LCM(910,380) = 345800 / 10
LCM(910,380) = 34580
