So the greatest common factor 213,210 is 3.
Lets's calculate LCM of 344,778
2 | 344, 778 |
172, 389 |
∴ So the LCM of the given numbers is 2 x 172 x 389 = 133816
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/133816
Therefore, the GCF of Fractions 213/344,210/778 is 3/133816
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 344,778 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(344,778) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(344,778) x common factors =2 x 1 = 2
LCM(344,778) = ( 344 × 778 ) / 2
LCM(344,778) = 267632 / 2
LCM(344,778) = 133816
