So the greatest common factor 842,336 is 2.
Lets's calculate LCM of 480,423
3 | 480, 423 |
160, 141 |
∴ So the LCM of the given numbers is 3 x 160 x 141 = 67680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/67680
Therefore, the GCF of Fractions 842/480,336/423 is 2/67680
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 480,423 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(480,423) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(480,423) x common factors =3 x 1 = 3
LCM(480,423) = ( 480 × 423 ) / 3
LCM(480,423) = 203040 / 3
LCM(480,423) = 67680
