So the greatest common factor 783,672 is 3.
Lets's calculate LCM of 279,759
| 3 | 279, 759 |
| 93, 253 |
∴ So the LCM of the given numbers is 3 x 93 x 253 = 70587
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/70587
Therefore, the GCF of Fractions 783/279,672/759 is 3/70587
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 279,759 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(279,759) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(279,759) x common factors =3 x 1 = 3
LCM(279,759) = ( 279 × 759 ) / 3
LCM(279,759) = 211761 / 3
LCM(279,759) = 70587
