1,2,4,5,10,20,29,58,116,145,290,580
Greatest Common Factor
We found the factors 86,87,580 . The biggest common factor number is the GCF number.
So the greatest common factor 86,87,580 is 1.
Lets's calculate LCM of 40,81,382
2 | 40, 81, 382 |
20, 81, 191 |
∴ So the LCM of the given numbers is 2 x 20 x 81 x 191 = 618840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/618840
Therefore, the GCF of Fractions 86/40,87/81,580/382 is 1/618840
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 40,81,382 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,81,382) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(40,81,382) x common factors =1 x 2 = 2
LCM(40,81,382) = ( 40 × 81 × 382 ) / 2
LCM(40,81,382) = 1237680 / 2
LCM(40,81,382) = 618840
