So the greatest common factor 11,644,345 is 1.
Lets's calculate LCM of 978,886,904
2 | 978, 886, 904 |
489, 443, 452 |
∴ So the LCM of the given numbers is 2 x 489 x 443 x 452 = 195830808
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/195830808
Therefore, the GCF of Fractions 11/978,644/886,345/904 is 1/195830808
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 978,886,904 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(978,886,904) = 2
common factors(in case of two or more numbers have common factors) = 2
GCF(978,886,904) x common factors =2 x 2 = 4
LCM(978,886,904) = ( 978 × 886 × 904 ) / 4
LCM(978,886,904) = 783323232 / 4
LCM(978,886,904) = 195830808
