So the greatest common factor 8,89,24,855 is 1.
Lets's calculate LCM of 28,81,136,510
2 | 28, 81, 136, 510 |
2 | 14, 81, 68, 255 |
3 | 7, 81, 34, 255 |
17 | 7, 27, 34, 85 |
7, 27, 2, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 17 x 7 x 27 x 2 x 5 = 385560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/385560
Therefore, the GCF of Fractions 8/28,89/81,24/136,855/510 is 1/385560
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 28,81,136,510 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,81,136,510) = 1
common factors(in case of two or more numbers have common factors) = 408
GCF(28,81,136,510) x common factors =1 x 408 = 408
LCM(28,81,136,510) = ( 28 × 81 × 136 × 510 ) / 408
LCM(28,81,136,510) = 157308480 / 408
LCM(28,81,136,510) = 385560
