Greatest Common Factor
We found the factors 258,394 . The biggest common factor number is the GCF number.
So the greatest common factor 258,394 is 2.
Lets's calculate LCM of 244,778
2 | 244, 778 |
122, 389 |
∴ So the LCM of the given numbers is 2 x 122 x 389 = 94916
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/94916
Therefore, the GCF of Fractions 258/244,394/778 is 2/94916
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 244,778 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(244,778) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(244,778) x common factors =2 x 1 = 2
LCM(244,778) = ( 244 × 778 ) / 2
LCM(244,778) = 189832 / 2
LCM(244,778) = 94916
