So the greatest common factor 684,379 is 1.
Lets's calculate LCM of 648,195
3 | 648, 195 |
216, 65 |
∴ So the LCM of the given numbers is 3 x 216 x 65 = 42120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/42120
Therefore, the GCF of Fractions 684/648,379/195 is 1/42120
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 648,195 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(648,195) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(648,195) x common factors =3 x 1 = 3
LCM(648,195) = ( 648 × 195 ) / 3
LCM(648,195) = 126360 / 3
LCM(648,195) = 42120
