So the greatest common factor 225,408 is 3.
Lets's calculate LCM of 707,406
7 | 707, 406 |
101, 58 |
∴ So the LCM of the given numbers is 7 x 101 x 58 = 41006
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/41006
Therefore, the GCF of Fractions 225/707,408/406 is 3/41006
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 707,406 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(707,406) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(707,406) x common factors =7 x 1 = 7
LCM(707,406) = ( 707 × 406 ) / 7
LCM(707,406) = 287042 / 7
LCM(707,406) = 41006
