Lets's calculate LCM of 76,928
| 2 | 76, 928 |
| 2 | 38, 464 |
| 19, 232 |
∴ So the LCM of the given numbers is 2 x 2 x 19 x 232 = 17632
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17632
Therefore, the GCF of Fractions 798/76,1399/928 is 1/17632
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 76,928 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,928) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(76,928) x common factors =4 x 1 = 4
LCM(76,928) = ( 76 × 928 ) / 4
LCM(76,928) = 70528 / 4
LCM(76,928) = 17632
