Lets's calculate LCM of 885,696
3 | 885, 696 |
295, 232 |
∴ So the LCM of the given numbers is 3 x 295 x 232 = 205320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/205320
Therefore, the GCF of Fractions 430/885,154/696 is 2/205320
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 885,696 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(885,696) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(885,696) x common factors =3 x 1 = 3
LCM(885,696) = ( 885 × 696 ) / 3
LCM(885,696) = 615960 / 3
LCM(885,696) = 205320
