So the greatest common factor 1805,2109 is 19.
Lets's calculate LCM of 742,454
2 | 742, 454 |
371, 227 |
∴ So the LCM of the given numbers is 2 x 371 x 227 = 168434
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 19/168434
Therefore, the GCF of Fractions 1805/742,2109/454 is 19/168434
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 742,454 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(742,454) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(742,454) x common factors =2 x 1 = 2
LCM(742,454) = ( 742 × 454 ) / 2
LCM(742,454) = 336868 / 2
LCM(742,454) = 168434
