So the greatest common factor 77,88,622 is 1.
Lets's calculate LCM of 386,579,626
2 | 386, 579, 626 |
193 | 193, 579, 313 |
1, 3, 313 |
∴ So the LCM of the given numbers is 2 x 193 x 1 x 3 x 313 = 362454
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/362454
Therefore, the GCF of Fractions 77/386,88/579,622/626 is 1/362454
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 386,579,626 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(386,579,626) = 1
common factors(in case of two or more numbers have common factors) = 386
GCF(386,579,626) x common factors =1 x 386 = 386
LCM(386,579,626) = ( 386 × 579 × 626 ) / 386
LCM(386,579,626) = 139907244 / 386
LCM(386,579,626) = 362454
