Greatest Common Factor
We found the factors 659,1708 . The biggest common factor number is the GCF number.
So the greatest common factor 659,1708 is 1.
Lets's calculate LCM of 472,690
2 | 472, 690 |
236, 345 |
∴ So the LCM of the given numbers is 2 x 236 x 345 = 162840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/162840
Therefore, the GCF of Fractions 659/472,1708/690 is 1/162840
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 472,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(472,690) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(472,690) x common factors =2 x 1 = 2
LCM(472,690) = ( 472 × 690 ) / 2
LCM(472,690) = 325680 / 2
LCM(472,690) = 162840
