So the greatest common factor 86,66 is 2.
Lets's calculate LCM of 658,3619
7 | 658, 3619 |
47 | 94, 517 |
2, 11 |
∴ So the LCM of the given numbers is 7 x 47 x 2 x 11 = 7238
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/7238
Therefore, the GCF of Fractions 86/658,66/3619 is 2/7238
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 658,3619 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(658,3619) = 329
common factors(in case of two or more numbers have common factors) = 1
GCF(658,3619) x common factors =329 x 1 = 329
LCM(658,3619) = ( 658 × 3619 ) / 329
LCM(658,3619) = 2381302 / 329
LCM(658,3619) = 7238
