Lets's calculate LCM of 706,123,579
3 | 706, 123, 579 |
706, 41, 193 |
∴ So the LCM of the given numbers is 3 x 706 x 41 x 193 = 16759734
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/16759734
Therefore, the GCF of Fractions 30/706,98/123,580/579 is 2/16759734
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 706,123,579 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(706,123,579) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(706,123,579) x common factors =1 x 3 = 3
LCM(706,123,579) = ( 706 × 123 × 579 ) / 3
LCM(706,123,579) = 50279202 / 3
LCM(706,123,579) = 16759734
