So the greatest common factor 620,344 is 4.
Lets's calculate LCM of 694,790
2 | 694, 790 |
347, 395 |
∴ So the LCM of the given numbers is 2 x 347 x 395 = 274130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/274130
Therefore, the GCF of Fractions 620/694,344/790 is 4/274130
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 694,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(694,790) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(694,790) x common factors =2 x 1 = 2
LCM(694,790) = ( 694 × 790 ) / 2
LCM(694,790) = 548260 / 2
LCM(694,790) = 274130
