So the greatest common factor 89,279,649 is 1.
Lets's calculate LCM of 71,85,923
71 | 71, 85, 923 |
1, 85, 13 |
∴ So the LCM of the given numbers is 71 x 1 x 85 x 13 = 78455
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/78455
Therefore, the GCF of Fractions 89/71,279/85,649/923 is 1/78455
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 71,85,923 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,85,923) = 1
common factors(in case of two or more numbers have common factors) = 71
GCF(71,85,923) x common factors =1 x 71 = 71
LCM(71,85,923) = ( 71 × 85 × 923 ) / 71
LCM(71,85,923) = 5570305 / 71
LCM(71,85,923) = 78455
