Lets's calculate LCM of 898,278,116
2 | 898, 278, 116 |
449, 139, 58 |
∴ So the LCM of the given numbers is 2 x 449 x 139 x 58 = 7239676
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7239676
Therefore, the GCF of Fractions 80/898,663/278,990/116 is 1/7239676
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 898,278,116 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(898,278,116) = 2
common factors(in case of two or more numbers have common factors) = 2
GCF(898,278,116) x common factors =2 x 2 = 4
LCM(898,278,116) = ( 898 × 278 × 116 ) / 4
LCM(898,278,116) = 28958704 / 4
LCM(898,278,116) = 7239676
