So the greatest common factor 549,1242 is 9.
Lets's calculate LCM of 583,297
11 | 583, 297 |
53, 27 |
∴ So the LCM of the given numbers is 11 x 53 x 27 = 15741
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/15741
Therefore, the GCF of Fractions 549/583,1242/297 is 9/15741
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 583,297 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(583,297) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(583,297) x common factors =11 x 1 = 11
LCM(583,297) = ( 583 × 297 ) / 11
LCM(583,297) = 173151 / 11
LCM(583,297) = 15741
