So the greatest common factor 15,578,993 is 1.
Lets's calculate LCM of 255,238,318
2 | 255, 238, 318 |
3 | 255, 119, 159 |
17 | 85, 119, 53 |
5, 7, 53 |
∴ So the LCM of the given numbers is 2 x 3 x 17 x 5 x 7 x 53 = 189210
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/189210
Therefore, the GCF of Fractions 15/255,578/238,993/318 is 1/189210
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 255,238,318 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(255,238,318) = 1
common factors(in case of two or more numbers have common factors) = 102
GCF(255,238,318) x common factors =1 x 102 = 102
LCM(255,238,318) = ( 255 × 238 × 318 ) / 102
LCM(255,238,318) = 19299420 / 102
LCM(255,238,318) = 189210
