So the greatest common factor 268,225,256 is 1.
Lets's calculate LCM of 858,743,238
2 | 858, 743, 238 |
429, 743, 119 |
∴ So the LCM of the given numbers is 2 x 429 x 743 x 119 = 75861786
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/75861786
Therefore, the GCF of Fractions 268/858,225/743,256/238 is 1/75861786
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 858,743,238 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(858,743,238) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(858,743,238) x common factors =1 x 2 = 2
LCM(858,743,238) = ( 858 × 743 × 238 ) / 2
LCM(858,743,238) = 151723572 / 2
LCM(858,743,238) = 75861786
