:1,2,4,5,10,20,47,94,188,235,470,940
Greatest Common Factor
We found the factors 700,940 . The biggest common factor number is the GCF number.
So the greatest common factor 700,940 is 20.
Lets's calculate LCM of 904,790
2 | 904, 790 |
452, 395 |
∴ So the LCM of the given numbers is 2 x 452 x 395 = 357080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/357080
Therefore, the GCF of Fractions 700/904,940/790 is 20/357080
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 904,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(904,790) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(904,790) x common factors =2 x 1 = 2
LCM(904,790) = ( 904 × 790 ) / 2
LCM(904,790) = 714160 / 2
LCM(904,790) = 357080
