Greatest Common Factor
We found the factors 26,457,927 . The biggest common factor number is the GCF number.
So the greatest common factor 26,457,927 is 1.
Lets's calculate LCM of 21,35,990
3 | 21, 35, 990 |
5 | 7, 35, 330 |
7 | 7, 7, 66 |
1, 1, 66 |
∴ So the LCM of the given numbers is 3 x 5 x 7 x 1 x 1 x 66 = 6930
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6930
Therefore, the GCF of Fractions 26/21,457/35,927/990 is 1/6930
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 21,35,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,35,990) = 1
common factors(in case of two or more numbers have common factors) = 105
GCF(21,35,990) x common factors =1 x 105 = 105
LCM(21,35,990) = ( 21 × 35 × 990 ) / 105
LCM(21,35,990) = 727650 / 105
LCM(21,35,990) = 6930
