So the greatest common factor 8,2,68,68 is 2.
Lets's calculate LCM of 27,87,72,415
3 | 27, 87, 72, 415 |
3 | 9, 29, 24, 415 |
3, 29, 8, 415 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 29 x 8 x 415 = 2599560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2599560
Therefore, the GCF of Fractions 8/27,2/87,68/72,68/415 is 2/2599560
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 27,87,72,415 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(27,87,72,415) = 1
common factors(in case of two or more numbers have common factors) = 27
GCF(27,87,72,415) x common factors =1 x 27 = 27
LCM(27,87,72,415) = ( 27 × 87 × 72 × 415 ) / 27
LCM(27,87,72,415) = 70188120 / 27
LCM(27,87,72,415) = 2599560
