So the greatest common factor 783,774 is 9.
Lets's calculate LCM of 985,845
5 | 985, 845 |
197, 169 |
∴ So the LCM of the given numbers is 5 x 197 x 169 = 166465
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/166465
Therefore, the GCF of Fractions 783/985,774/845 is 9/166465
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 985,845 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(985,845) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(985,845) x common factors =5 x 1 = 5
LCM(985,845) = ( 985 × 845 ) / 5
LCM(985,845) = 832325 / 5
LCM(985,845) = 166465
