1,3,5,15,23,69,115,345
Greatest Common Factor
We found the factors 240,345 . The biggest common factor number is the GCF number.
So the greatest common factor 240,345 is 15.
Lets's calculate LCM of 114,484
2 | 114, 484 |
57, 242 |
∴ So the LCM of the given numbers is 2 x 57 x 242 = 27588
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/27588
Therefore, the GCF of Fractions 240/114,345/484 is 15/27588
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 114,484 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(114,484) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(114,484) x common factors =2 x 1 = 2
LCM(114,484) = ( 114 × 484 ) / 2
LCM(114,484) = 55176 / 2
LCM(114,484) = 27588
