So the greatest common factor 408,629 is 17.
Lets's calculate LCM of 393,102
3 | 393, 102 |
131, 34 |
∴ So the LCM of the given numbers is 3 x 131 x 34 = 13362
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/13362
Therefore, the GCF of Fractions 408/393,629/102 is 17/13362
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 393,102 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(393,102) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(393,102) x common factors =3 x 1 = 3
LCM(393,102) = ( 393 × 102 ) / 3
LCM(393,102) = 40086 / 3
LCM(393,102) = 13362
