We found the factors 428,116,124 . The biggest common factor number is the GCF number.
So the greatest common factor 428,116,124 is 4.
Lets's calculate LCM of 81,39,471
3 | 81, 39, 471 |
27, 13, 157 |
∴ So the LCM of the given numbers is 3 x 27 x 13 x 157 = 165321
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/165321
Therefore, the GCF of Fractions 428/81,116/39,124/471 is 4/165321
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 81,39,471 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,39,471) = 3
common factors(in case of two or more numbers have common factors) = 3
GCF(81,39,471) x common factors =3 x 3 = 9
LCM(81,39,471) = ( 81 × 39 × 471 ) / 9
LCM(81,39,471) = 1487889 / 9
LCM(81,39,471) = 165321
