So the greatest common factor 85,68,510 is 17.
Lets's calculate LCM of 155,945,225
3 | 155, 945, 225 |
3 | 155, 315, 75 |
5 | 155, 105, 25 |
31, 21, 5 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 31 x 21 x 5 = 146475
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/146475
Therefore, the GCF of Fractions 85/155,68/945,510/225 is 17/146475
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 155,945,225 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(155,945,225) = 5
common factors(in case of two or more numbers have common factors) = 45
GCF(155,945,225) x common factors =5 x 45 = 225
LCM(155,945,225) = ( 155 × 945 × 225 ) / 225
LCM(155,945,225) = 32956875 / 225
LCM(155,945,225) = 146475
