So the greatest common factor 8,62,72,821 is 1.
Lets's calculate LCM of 86,75,754,891
2 | 86, 75, 754, 891 |
3 | 43, 75, 377, 891 |
43, 25, 377, 297 |
∴ So the LCM of the given numbers is 2 x 3 x 43 x 25 x 377 x 297 = 722200050
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/722200050
Therefore, the GCF of Fractions 8/86,62/75,72/754,821/891 is 1/722200050
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 86,75,754,891 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,75,754,891) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(86,75,754,891) x common factors =1 x 6 = 6
LCM(86,75,754,891) = ( 86 × 75 × 754 × 891 ) / 6
LCM(86,75,754,891) = 4333200300 / 6
LCM(86,75,754,891) = 722200050
