Lets's calculate LCM of 663,558
3 | 663, 558 |
221, 186 |
∴ So the LCM of the given numbers is 3 x 221 x 186 = 123318
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/123318
Therefore, the GCF of Fractions 608/663,615/558 is 1/123318
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 663,558 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(663,558) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(663,558) x common factors =3 x 1 = 3
LCM(663,558) = ( 663 × 558 ) / 3
LCM(663,558) = 369954 / 3
LCM(663,558) = 123318
