Greatest Common Factor
We found the factors 669,606 . The biggest common factor number is the GCF number.
So the greatest common factor 669,606 is 3.
Lets's calculate LCM of 393,987
3 | 393, 987 |
131, 329 |
∴ So the LCM of the given numbers is 3 x 131 x 329 = 129297
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/129297
Therefore, the GCF of Fractions 669/393,606/987 is 3/129297
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 393,987 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(393,987) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(393,987) x common factors =3 x 1 = 3
LCM(393,987) = ( 393 × 987 ) / 3
LCM(393,987) = 387891 / 3
LCM(393,987) = 129297
