Lets's calculate LCM of 646,630
2 | 646, 630 |
323, 315 |
∴ So the LCM of the given numbers is 2 x 323 x 315 = 203490
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/203490
Therefore, the GCF of Fractions 803/646,7865/630 is 11/203490
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 646,630 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(646,630) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(646,630) x common factors =2 x 1 = 2
LCM(646,630) = ( 646 × 630 ) / 2
LCM(646,630) = 406980 / 2
LCM(646,630) = 203490
