Greatest Common Factor
We found the factors 816,302 . The biggest common factor number is the GCF number.
So the greatest common factor 816,302 is 2.
Lets's calculate LCM of 215,344
43 | 215, 344 |
5, 8 |
∴ So the LCM of the given numbers is 43 x 5 x 8 = 1720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1720
Therefore, the GCF of Fractions 816/215,302/344 is 2/1720
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 215,344 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(215,344) = 43
common factors(in case of two or more numbers have common factors) = 1
GCF(215,344) x common factors =43 x 1 = 43
LCM(215,344) = ( 215 × 344 ) / 43
LCM(215,344) = 73960 / 43
LCM(215,344) = 1720
