1,2,4,5,8,10,16,20,40,80,83,166,332,415,664,830,1328,1660,3320,6640
Greatest Common Factor
We found the factors 254,6640 . The biggest common factor number is the GCF number.
So the greatest common factor 254,6640 is 2.
Lets's calculate LCM of 99,900
3 | 99, 900 |
3 | 33, 300 |
11, 100 |
∴ So the LCM of the given numbers is 3 x 3 x 11 x 100 = 9900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/9900
Therefore, the GCF of Fractions 254/99,6640/900 is 2/9900
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 99,900 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,900) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(99,900) x common factors =9 x 1 = 9
LCM(99,900) = ( 99 × 900 ) / 9
LCM(99,900) = 89100 / 9
LCM(99,900) = 9900
