We found the factors 724,1710 . The biggest common factor number is the GCF number.
So the greatest common factor 724,1710 is 2.
Lets's calculate LCM of 378,836
2 | 378, 836 |
189, 418 |
∴ So the LCM of the given numbers is 2 x 189 x 418 = 158004
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/158004
Therefore, the GCF of Fractions 724/378,1710/836 is 2/158004
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 378,836 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(378,836) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(378,836) x common factors =2 x 1 = 2
LCM(378,836) = ( 378 × 836 ) / 2
LCM(378,836) = 316008 / 2
LCM(378,836) = 158004
