So the greatest common factor 57,466,417 is 1.
Lets's calculate LCM of 18,84,387
2 | 18, 84, 387 |
3 | 9, 42, 387 |
3 | 3, 14, 129 |
1, 14, 43 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 1 x 14 x 43 = 10836
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10836
Therefore, the GCF of Fractions 57/18,466/84,417/387 is 1/10836
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 18,84,387 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,84,387) = 3
common factors(in case of two or more numbers have common factors) = 18
GCF(18,84,387) x common factors =3 x 18 = 54
LCM(18,84,387) = ( 18 × 84 × 387 ) / 54
LCM(18,84,387) = 585144 / 54
LCM(18,84,387) = 10836
