Greatest Common Factor
We found the factors 863,549 . The biggest common factor number is the GCF number.
So the greatest common factor 863,549 is 1.
Lets's calculate LCM of 561,207
3 | 561, 207 |
187, 69 |
∴ So the LCM of the given numbers is 3 x 187 x 69 = 38709
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/38709
Therefore, the GCF of Fractions 863/561,549/207 is 1/38709
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 561,207 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(561,207) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(561,207) x common factors =3 x 1 = 3
LCM(561,207) = ( 561 × 207 ) / 3
LCM(561,207) = 116127 / 3
LCM(561,207) = 38709
