:1,2,5,10,797,1594,3985,7970
Now, list down the factors of 4030
:1,2,5,10,13,26,31,62,65,130,155,310,403,806,2015,4030
Greatest Common Factor
We found the factors 7970,4030 . The biggest common factor number is the GCF number.
So the greatest common factor 7970,4030 is 10.
Lets's calculate LCM of 298,990
2 | 298, 990 |
149, 495 |
∴ So the LCM of the given numbers is 2 x 149 x 495 = 147510
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/147510
Therefore, the GCF of Fractions 7970/298,4030/990 is 10/147510
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 298,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(298,990) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(298,990) x common factors =2 x 1 = 2
LCM(298,990) = ( 298 × 990 ) / 2
LCM(298,990) = 295020 / 2
LCM(298,990) = 147510
