So the greatest common factor 744,1356 is 12.
Lets's calculate LCM of 687,123
3 | 687, 123 |
229, 41 |
∴ So the LCM of the given numbers is 3 x 229 x 41 = 28167
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/28167
Therefore, the GCF of Fractions 744/687,1356/123 is 12/28167
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 687,123 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(687,123) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(687,123) x common factors =3 x 1 = 3
LCM(687,123) = ( 687 × 123 ) / 3
LCM(687,123) = 84501 / 3
LCM(687,123) = 28167
