So the greatest common factor 71,83,690 is 1.
Lets's calculate LCM of 711,675,440
3 | 711, 675, 440 |
3 | 237, 225, 440 |
5 | 79, 75, 440 |
79, 15, 88 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 79 x 15 x 88 = 4692600
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4692600
Therefore, the GCF of Fractions 71/711,83/675,690/440 is 1/4692600
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 711,675,440 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(711,675,440) = 1
common factors(in case of two or more numbers have common factors) = 45
GCF(711,675,440) x common factors =1 x 45 = 45
LCM(711,675,440) = ( 711 × 675 × 440 ) / 45
LCM(711,675,440) = 211167000 / 45
LCM(711,675,440) = 4692600
