Greatest Common Factor
We found the factors 285,699 . The biggest common factor number is the GCF number.
So the greatest common factor 285,699 is 3.
Lets's calculate LCM of 27,3843
3 | 27, 3843 |
3 | 9, 1281 |
3, 427 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 427 = 11529
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/11529
Therefore, the GCF of Fractions 285/27,699/3843 is 3/11529
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 27,3843 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(27,3843) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(27,3843) x common factors =9 x 1 = 9
LCM(27,3843) = ( 27 × 3843 ) / 9
LCM(27,3843) = 103761 / 9
LCM(27,3843) = 11529
