So the greatest common factor 1831,1272 is 1.
Lets's calculate LCM of 678,1958
2 | 678, 1958 |
339, 979 |
∴ So the LCM of the given numbers is 2 x 339 x 979 = 663762
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/663762
Therefore, the GCF of Fractions 1831/678,1272/1958 is 1/663762
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 678,1958 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(678,1958) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(678,1958) x common factors =2 x 1 = 2
LCM(678,1958) = ( 678 × 1958 ) / 2
LCM(678,1958) = 1327524 / 2
LCM(678,1958) = 663762
