Greatest Common Factor
We found the factors 940,810 . The biggest common factor number is the GCF number.
So the greatest common factor 940,810 is 10.
Lets's calculate LCM of 399,238
7 | 399, 238 |
57, 34 |
∴ So the LCM of the given numbers is 7 x 57 x 34 = 13566
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/13566
Therefore, the GCF of Fractions 940/399,810/238 is 10/13566
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 399,238 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(399,238) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(399,238) x common factors =7 x 1 = 7
LCM(399,238) = ( 399 × 238 ) / 7
LCM(399,238) = 94962 / 7
LCM(399,238) = 13566
