Greatest Common Factor
We found the factors 27,67,275 . The biggest common factor number is the GCF number.
So the greatest common factor 27,67,275 is 1.
Lets's calculate LCM of 19,86,790
2 | 19, 86, 790 |
19, 43, 395 |
∴ So the LCM of the given numbers is 2 x 19 x 43 x 395 = 645430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/645430
Therefore, the GCF of Fractions 27/19,67/86,275/790 is 1/645430
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 19,86,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,86,790) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(19,86,790) x common factors =1 x 2 = 2
LCM(19,86,790) = ( 19 × 86 × 790 ) / 2
LCM(19,86,790) = 1290860 / 2
LCM(19,86,790) = 645430
