Lets's calculate LCM of 208,288
2 | 208, 288 |
2 | 104, 144 |
2 | 52, 72 |
2 | 26, 36 |
13, 18 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 13 x 18 = 3744
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 47/3744
Therefore, the GCF of Fractions 470/208,1081/288 is 47/3744
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 208,288 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(208,288) = 16
common factors(in case of two or more numbers have common factors) = 1
GCF(208,288) x common factors =16 x 1 = 16
LCM(208,288) = ( 208 × 288 ) / 16
LCM(208,288) = 59904 / 16
LCM(208,288) = 3744
