:1,281
Now, list down the factors of 830
:1,2,5,10,83,166,415,830
Greatest Common Factor
We found the factors 281,830 . The biggest common factor number is the GCF number.
So the greatest common factor 281,830 is 1.
Lets's calculate LCM of 231,721
7 | 231, 721 |
33, 103 |
∴ So the LCM of the given numbers is 7 x 33 x 103 = 23793
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/23793
Therefore, the GCF of Fractions 281/231,830/721 is 1/23793
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 231,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(231,721) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(231,721) x common factors =7 x 1 = 7
LCM(231,721) = ( 231 × 721 ) / 7
LCM(231,721) = 166551 / 7
LCM(231,721) = 23793
