So the greatest common factor 985,258 is 1.
Lets's calculate LCM of 57,1371
3 | 57, 1371 |
19, 457 |
∴ So the LCM of the given numbers is 3 x 19 x 457 = 26049
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/26049
Therefore, the GCF of Fractions 985/57,258/1371 is 1/26049
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 57,1371 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,1371) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(57,1371) x common factors =3 x 1 = 3
LCM(57,1371) = ( 57 × 1371 ) / 3
LCM(57,1371) = 78147 / 3
LCM(57,1371) = 26049
