So the greatest common factor 672,300 is 12.
Lets's calculate LCM of 391,799
17 | 391, 799 |
23, 47 |
∴ So the LCM of the given numbers is 17 x 23 x 47 = 18377
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/18377
Therefore, the GCF of Fractions 672/391,300/799 is 12/18377
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 391,799 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(391,799) = 17
common factors(in case of two or more numbers have common factors) = 1
GCF(391,799) x common factors =17 x 1 = 17
LCM(391,799) = ( 391 × 799 ) / 17
LCM(391,799) = 312409 / 17
LCM(391,799) = 18377
