So the greatest common factor 312,671 is 1.
Lets's calculate LCM of 80,238
2 | 80, 238 |
40, 119 |
∴ So the LCM of the given numbers is 2 x 40 x 119 = 9520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9520
Therefore, the GCF of Fractions 312/80,671/238 is 1/9520
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 80,238 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,238) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(80,238) x common factors =2 x 1 = 2
LCM(80,238) = ( 80 × 238 ) / 2
LCM(80,238) = 19040 / 2
LCM(80,238) = 9520
