So the greatest common factor 148,644 is 4.
Lets's calculate LCM of 555,864
3 | 555, 864 |
185, 288 |
∴ So the LCM of the given numbers is 3 x 185 x 288 = 159840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/159840
Therefore, the GCF of Fractions 148/555,644/864 is 4/159840
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 555,864 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(555,864) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(555,864) x common factors =3 x 1 = 3
LCM(555,864) = ( 555 × 864 ) / 3
LCM(555,864) = 479520 / 3
LCM(555,864) = 159840
