So the greatest common factor 66,251,949 is 1.
Lets's calculate LCM of 80,34,419
2 | 80, 34, 419 |
40, 17, 419 |
∴ So the LCM of the given numbers is 2 x 40 x 17 x 419 = 569840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/569840
Therefore, the GCF of Fractions 66/80,251/34,949/419 is 1/569840
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 80,34,419 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,34,419) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(80,34,419) x common factors =1 x 2 = 2
LCM(80,34,419) = ( 80 × 34 × 419 ) / 2
LCM(80,34,419) = 1139680 / 2
LCM(80,34,419) = 569840
