Lets's calculate LCM of 234,879
3 | 234, 879 |
78, 293 |
∴ So the LCM of the given numbers is 3 x 78 x 293 = 68562
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/68562
Therefore, the GCF of Fractions 478/234,855/879 is 1/68562
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 234,879 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(234,879) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(234,879) x common factors =3 x 1 = 3
LCM(234,879) = ( 234 × 879 ) / 3
LCM(234,879) = 205686 / 3
LCM(234,879) = 68562
