So the greatest common factor 86,911,640 is 1.
Lets's calculate LCM of 306,969,907
3 | 306, 969, 907 |
17 | 102, 323, 907 |
6, 19, 907 |
∴ So the LCM of the given numbers is 3 x 17 x 6 x 19 x 907 = 5273298
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5273298
Therefore, the GCF of Fractions 86/306,911/969,640/907 is 1/5273298
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 306,969,907 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(306,969,907) = 1
common factors(in case of two or more numbers have common factors) = 51
GCF(306,969,907) x common factors =1 x 51 = 51
LCM(306,969,907) = ( 306 × 969 × 907 ) / 51
LCM(306,969,907) = 268938198 / 51
LCM(306,969,907) = 5273298
