Lets's calculate LCM of 656,451,389
41 | 656, 451, 389 |
16, 11, 389 |
∴ So the LCM of the given numbers is 41 x 16 x 11 x 389 = 2807024
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2807024
Therefore, the GCF of Fractions 61/656,80/451,819/389 is 1/2807024
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 656,451,389 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(656,451,389) = 1
common factors(in case of two or more numbers have common factors) = 41
GCF(656,451,389) x common factors =1 x 41 = 41
LCM(656,451,389) = ( 656 × 451 × 389 ) / 41
LCM(656,451,389) = 115087984 / 41
LCM(656,451,389) = 2807024
