Lets's calculate LCM of 687,648
3 | 687, 648 |
229, 216 |
∴ So the LCM of the given numbers is 3 x 229 x 216 = 148392
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/148392
Therefore, the GCF of Fractions 608/687,850/648 is 2/148392
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 687,648 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(687,648) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(687,648) x common factors =3 x 1 = 3
LCM(687,648) = ( 687 × 648 ) / 3
LCM(687,648) = 445176 / 3
LCM(687,648) = 148392
