Greatest Common Factor
We found the factors 240,210 . The biggest common factor number is the GCF number.
So the greatest common factor 240,210 is 30.
Lets's calculate LCM of 1710,1090
2 | 1710, 1090 |
5 | 855, 545 |
171, 109 |
∴ So the LCM of the given numbers is 2 x 5 x 171 x 109 = 186390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 30/186390
Therefore, the GCF of Fractions 240/1710,210/1090 is 30/186390
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 1710,1090 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1710,1090) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(1710,1090) x common factors =10 x 1 = 10
LCM(1710,1090) = ( 1710 × 1090 ) / 10
LCM(1710,1090) = 1863900 / 10
LCM(1710,1090) = 186390
