So the greatest common factor 665,836 is 19.
Lets's calculate LCM of 324,634
2 | 324, 634 |
162, 317 |
∴ So the LCM of the given numbers is 2 x 162 x 317 = 102708
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 19/102708
Therefore, the GCF of Fractions 665/324,836/634 is 19/102708
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 324,634 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(324,634) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(324,634) x common factors =2 x 1 = 2
LCM(324,634) = ( 324 × 634 ) / 2
LCM(324,634) = 205416 / 2
LCM(324,634) = 102708
