Lets's calculate LCM of 862,388
2 | 862, 388 |
431, 194 |
∴ So the LCM of the given numbers is 2 x 431 x 194 = 167228
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/167228
Therefore, the GCF of Fractions 312/862,393/388 is 3/167228
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 862,388 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(862,388) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(862,388) x common factors =2 x 1 = 2
LCM(862,388) = ( 862 × 388 ) / 2
LCM(862,388) = 334456 / 2
LCM(862,388) = 167228
