So the greatest common factor 784,456 is 8.
Lets's calculate LCM of 69,9576
3 | 69, 9576 |
23, 3192 |
∴ So the LCM of the given numbers is 3 x 23 x 3192 = 220248
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/220248
Therefore, the GCF of Fractions 784/69,456/9576 is 8/220248
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 69,9576 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,9576) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(69,9576) x common factors =3 x 1 = 3
LCM(69,9576) = ( 69 × 9576 ) / 3
LCM(69,9576) = 660744 / 3
LCM(69,9576) = 220248
