Greatest Common Factor
We found the factors 254,7086 . The biggest common factor number is the GCF number.
So the greatest common factor 254,7086 is 2.
Lets's calculate LCM of 890,682
2 | 890, 682 |
445, 341 |
∴ So the LCM of the given numbers is 2 x 445 x 341 = 303490
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/303490
Therefore, the GCF of Fractions 254/890,7086/682 is 2/303490
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 890,682 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(890,682) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(890,682) x common factors =2 x 1 = 2
LCM(890,682) = ( 890 × 682 ) / 2
LCM(890,682) = 606980 / 2
LCM(890,682) = 303490
