Lets's calculate LCM of 790,434
2 | 790, 434 |
395, 217 |
∴ So the LCM of the given numbers is 2 x 395 x 217 = 171430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/171430
Therefore, the GCF of Fractions 308/790,9905/434 is 7/171430
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 790,434 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(790,434) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(790,434) x common factors =2 x 1 = 2
LCM(790,434) = ( 790 × 434 ) / 2
LCM(790,434) = 342860 / 2
LCM(790,434) = 171430
