So the greatest common factor 798,7805 is 7.
Lets's calculate LCM of 292,306
2 | 292, 306 |
146, 153 |
∴ So the LCM of the given numbers is 2 x 146 x 153 = 44676
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/44676
Therefore, the GCF of Fractions 798/292,7805/306 is 7/44676
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 292,306 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(292,306) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(292,306) x common factors =2 x 1 = 2
LCM(292,306) = ( 292 × 306 ) / 2
LCM(292,306) = 89352 / 2
LCM(292,306) = 44676
