So the greatest common factor 998,615 is 1.
Lets's calculate LCM of 561,387
3 | 561, 387 |
187, 129 |
∴ So the LCM of the given numbers is 3 x 187 x 129 = 72369
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/72369
Therefore, the GCF of Fractions 998/561,615/387 is 1/72369
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 561,387 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(561,387) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(561,387) x common factors =3 x 1 = 3
LCM(561,387) = ( 561 × 387 ) / 3
LCM(561,387) = 217107 / 3
LCM(561,387) = 72369
