So the greatest common factor 378,903 is 21.
Lets's calculate LCM of 562,338
2 | 562, 338 |
281, 169 |
∴ So the LCM of the given numbers is 2 x 281 x 169 = 94978
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/94978
Therefore, the GCF of Fractions 378/562,903/338 is 21/94978
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 562,338 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(562,338) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(562,338) x common factors =2 x 1 = 2
LCM(562,338) = ( 562 × 338 ) / 2
LCM(562,338) = 189956 / 2
LCM(562,338) = 94978
