Lets's calculate LCM of 872,657,957
3 | 872, 657, 957 |
872, 219, 319 |
∴ So the LCM of the given numbers is 3 x 872 x 219 x 319 = 182756376
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/182756376
Therefore, the GCF of Fractions 67/872,78/657,560/957 is 1/182756376
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 872,657,957 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(872,657,957) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(872,657,957) x common factors =1 x 3 = 3
LCM(872,657,957) = ( 872 × 657 × 957 ) / 3
LCM(872,657,957) = 548269128 / 3
LCM(872,657,957) = 182756376
