So the greatest common factor 399,134 is 1.
Lets's calculate LCM of 644,554
2 | 644, 554 |
322, 277 |
∴ So the LCM of the given numbers is 2 x 322 x 277 = 178388
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/178388
Therefore, the GCF of Fractions 399/644,134/554 is 1/178388
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 644,554 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(644,554) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(644,554) x common factors =2 x 1 = 2
LCM(644,554) = ( 644 × 554 ) / 2
LCM(644,554) = 356776 / 2
LCM(644,554) = 178388
