Lets's calculate LCM of 882,927,884
2 | 882, 927, 884 |
3 | 441, 927, 442 |
3 | 147, 309, 442 |
49, 103, 442 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 49 x 103 x 442 = 40153932
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/40153932
Therefore, the GCF of Fractions 430/882,398/927,780/884 is 2/40153932
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 882,927,884 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(882,927,884) = 1
common factors(in case of two or more numbers have common factors) = 18
GCF(882,927,884) x common factors =1 x 18 = 18
LCM(882,927,884) = ( 882 × 927 × 884 ) / 18
LCM(882,927,884) = 722770776 / 18
LCM(882,927,884) = 40153932
