Greatest Common Factor
We found the factors 561,747 . The biggest common factor number is the GCF number.
So the greatest common factor 561,747 is 3.
Lets's calculate LCM of 88,2299
11 | 88, 2299 |
8, 209 |
∴ So the LCM of the given numbers is 11 x 8 x 209 = 18392
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/18392
Therefore, the GCF of Fractions 561/88,747/2299 is 3/18392
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 88,2299 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(88,2299) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(88,2299) x common factors =11 x 1 = 11
LCM(88,2299) = ( 88 × 2299 ) / 11
LCM(88,2299) = 202312 / 11
LCM(88,2299) = 18392
