So the greatest common factor 835,407,688 is 1.
Lets's calculate LCM of 205,595,420
| 5 | 205, 595, 420 |
| 7 | 41, 119, 84 |
| 41, 17, 12 |
∴ So the LCM of the given numbers is 5 x 7 x 41 x 17 x 12 = 292740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/292740
Therefore, the GCF of Fractions 835/205,407/595,688/420 is 1/292740
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 205,595,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(205,595,420) = 5
common factors(in case of two or more numbers have common factors) = 35
GCF(205,595,420) x common factors =5 x 35 = 175
LCM(205,595,420) = ( 205 × 595 × 420 ) / 175
LCM(205,595,420) = 51229500 / 175
LCM(205,595,420) = 292740
