Greatest Common Factor
We found the factors 640,750 . The biggest common factor number is the GCF number.
So the greatest common factor 640,750 is 10.
Lets's calculate LCM of 506,790
2 | 506, 790 |
253, 395 |
∴ So the LCM of the given numbers is 2 x 253 x 395 = 199870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/199870
Therefore, the GCF of Fractions 640/506,750/790 is 10/199870
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 506,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(506,790) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(506,790) x common factors =2 x 1 = 2
LCM(506,790) = ( 506 × 790 ) / 2
LCM(506,790) = 399740 / 2
LCM(506,790) = 199870
