So the greatest common factor 69,258,688 is 1.
Lets's calculate LCM of 40,96,889
2 | 40, 96, 889 |
2 | 20, 48, 889 |
2 | 10, 24, 889 |
5, 12, 889 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 12 x 889 = 426720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/426720
Therefore, the GCF of Fractions 69/40,258/96,688/889 is 1/426720
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 40,96,889 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,96,889) = 1
common factors(in case of two or more numbers have common factors) = 8
GCF(40,96,889) x common factors =1 x 8 = 8
LCM(40,96,889) = ( 40 × 96 × 889 ) / 8
LCM(40,96,889) = 3413760 / 8
LCM(40,96,889) = 426720
