We found the factors 259,945 . The biggest common factor number is the GCF number.
So the greatest common factor 259,945 is 7.
Lets's calculate LCM of 121,429
11 | 121, 429 |
11, 39 |
∴ So the LCM of the given numbers is 11 x 11 x 39 = 4719
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/4719
Therefore, the GCF of Fractions 259/121,945/429 is 7/4719
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 121,429 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(121,429) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(121,429) x common factors =11 x 1 = 11
LCM(121,429) = ( 121 × 429 ) / 11
LCM(121,429) = 51909 / 11
LCM(121,429) = 4719
