Lets's calculate LCM of 89,69,393
3 | 89, 69, 393 |
89, 23, 131 |
∴ So the LCM of the given numbers is 3 x 89 x 23 x 131 = 804471
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/804471
Therefore, the GCF of Fractions 68/89,622/69,170/393 is 2/804471
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 89,69,393 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,69,393) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(89,69,393) x common factors =1 x 3 = 3
LCM(89,69,393) = ( 89 × 69 × 393 ) / 3
LCM(89,69,393) = 2413413 / 3
LCM(89,69,393) = 804471
