3 | 687, 672 |
229, 224 |
∴ So the LCM of the given numbers is 3 x 229 x 224 = 153888
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/153888
Therefore, the GCF of Fractions 488/687,4678/672 is 2/153888
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 687,672 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(687,672) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(687,672) x common factors =3 x 1 = 3
LCM(687,672) = ( 687 × 672 ) / 3
LCM(687,672) = 461664 / 3
LCM(687,672) = 153888
