Lets's calculate LCM of 698,6916
2 | 698, 6916 |
349, 3458 |
∴ So the LCM of the given numbers is 2 x 349 x 3458 = 2413684
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2413684
Therefore, the GCF of Fractions 728/698,1206/6916 is 2/2413684
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 698,6916 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(698,6916) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(698,6916) x common factors =2 x 1 = 2
LCM(698,6916) = ( 698 × 6916 ) / 2
LCM(698,6916) = 4827368 / 2
LCM(698,6916) = 2413684
