Lets's calculate LCM of 399,155,999
3 | 399, 155, 999 |
133, 155, 333 |
∴ So the LCM of the given numbers is 3 x 133 x 155 x 333 = 20594385
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20594385
Therefore, the GCF of Fractions 79/399,40/155,984/999 is 1/20594385
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 399,155,999 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(399,155,999) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(399,155,999) x common factors =1 x 3 = 3
LCM(399,155,999) = ( 399 × 155 × 999 ) / 3
LCM(399,155,999) = 61783155 / 3
LCM(399,155,999) = 20594385
