List of positive integer factors of 21 that divides 21 without a remainder.
1,3,7,21
Factors of 830
List of positive integer factors of 830 that divides 830 without a remainder.
1,2,5,10,83,166,415,830
Greatest Common Factor
We found the factors 17,21,830 . The biggest common factor number is the GCF number.
So the greatest common factor 17,21,830 is 1.
Lets's calculate LCM of 472,721,198
2 | 472, 721, 198 |
236, 721, 99 |
∴ So the LCM of the given numbers is 2 x 236 x 721 x 99 = 33690888
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/33690888
Therefore, the GCF of Fractions 17/472,21/721,830/198 is 1/33690888
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 472,721,198 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(472,721,198) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(472,721,198) x common factors =1 x 2 = 2
LCM(472,721,198) = ( 472 × 721 × 198 ) / 2
LCM(472,721,198) = 67381776 / 2
LCM(472,721,198) = 33690888
