Lets's calculate LCM of 390,957
3 | 390, 957 |
130, 319 |
∴ So the LCM of the given numbers is 3 x 130 x 319 = 124410
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 56/124410
Therefore, the GCF of Fractions 896/390,840/957 is 56/124410
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 390,957 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(390,957) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(390,957) x common factors =3 x 1 = 3
LCM(390,957) = ( 390 × 957 ) / 3
LCM(390,957) = 373230 / 3
LCM(390,957) = 124410
