So the greatest common factor 618,636 is 6.
Lets's calculate LCM of 87,819
3 | 87, 819 |
29, 273 |
∴ So the LCM of the given numbers is 3 x 29 x 273 = 23751
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/23751
Therefore, the GCF of Fractions 618/87,636/819 is 6/23751
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 87,819 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(87,819) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(87,819) x common factors =3 x 1 = 3
LCM(87,819) = ( 87 × 819 ) / 3
LCM(87,819) = 71253 / 3
LCM(87,819) = 23751
