We found the factors 68,858,945 . The biggest common factor number is the GCF number.
So the greatest common factor 68,858,945 is 1.
Lets's calculate LCM of 73,63,18
3 | 73, 63, 18 |
3 | 73, 21, 6 |
73, 7, 2 |
∴ So the LCM of the given numbers is 3 x 3 x 73 x 7 x 2 = 9198
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9198
Therefore, the GCF of Fractions 68/73,858/63,945/18 is 1/9198
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 73,63,18 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(73,63,18) = 1
common factors(in case of two or more numbers have common factors) = 9
GCF(73,63,18) x common factors =1 x 9 = 9
LCM(73,63,18) = ( 73 × 63 × 18 ) / 9
LCM(73,63,18) = 82782 / 9
LCM(73,63,18) = 9198
