Greatest Common Factor
We found the factors 430,525,300 . The biggest common factor number is the GCF number.
So the greatest common factor 430,525,300 is 5.
Lets's calculate LCM of 18,90,990
2 | 18, 90, 990 |
3 | 9, 45, 495 |
3 | 3, 15, 165 |
5 | 1, 5, 55 |
1, 1, 11 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 1 x 1 x 11 = 990
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/990
Therefore, the GCF of Fractions 430/18,525/90,300/990 is 5/990
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 18,90,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,90,990) = 18
common factors(in case of two or more numbers have common factors) = 90
GCF(18,90,990) x common factors =18 x 90 = 1620
LCM(18,90,990) = ( 18 × 90 × 990 ) / 1620
LCM(18,90,990) = 1603800 / 1620
LCM(18,90,990) = 990
