So the greatest common factor 905,481 is 1.
Lets's calculate LCM of 696,678
2 | 696, 678 |
3 | 348, 339 |
116, 113 |
∴ So the LCM of the given numbers is 2 x 3 x 116 x 113 = 78648
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/78648
Therefore, the GCF of Fractions 905/696,481/678 is 1/78648
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 696,678 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(696,678) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(696,678) x common factors =6 x 1 = 6
LCM(696,678) = ( 696 × 678 ) / 6
LCM(696,678) = 471888 / 6
LCM(696,678) = 78648
