So the greatest common factor 84,299,317 is 1.
Lets's calculate LCM of 783,779,561
3 | 783, 779, 561 |
261, 779, 187 |
∴ So the LCM of the given numbers is 3 x 261 x 779 x 187 = 114061959
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/114061959
Therefore, the GCF of Fractions 84/783,299/779,317/561 is 1/114061959
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 783,779,561 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(783,779,561) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(783,779,561) x common factors =1 x 3 = 3
LCM(783,779,561) = ( 783 × 779 × 561 ) / 3
LCM(783,779,561) = 342185877 / 3
LCM(783,779,561) = 114061959
