Lets's calculate LCM of 658,210
2 | 658, 210 |
7 | 329, 105 |
47, 15 |
∴ So the LCM of the given numbers is 2 x 7 x 47 x 15 = 9870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/9870
Therefore, the GCF of Fractions 736/658,386/210 is 2/9870
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 658,210 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(658,210) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(658,210) x common factors =14 x 1 = 14
LCM(658,210) = ( 658 × 210 ) / 14
LCM(658,210) = 138180 / 14
LCM(658,210) = 9870
