Greatest Common Factor
We found the factors 27,749,741 . The biggest common factor number is the GCF number.
So the greatest common factor 27,749,741 is 1.
Lets's calculate LCM of 69,42,678
2 | 69, 42, 678 |
3 | 69, 21, 339 |
23, 7, 113 |
∴ So the LCM of the given numbers is 2 x 3 x 23 x 7 x 113 = 109158
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/109158
Therefore, the GCF of Fractions 27/69,749/42,741/678 is 1/109158
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 69,42,678 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,42,678) = 3
common factors(in case of two or more numbers have common factors) = 6
GCF(69,42,678) x common factors =3 x 6 = 18
LCM(69,42,678) = ( 69 × 42 × 678 ) / 18
LCM(69,42,678) = 1964844 / 18
LCM(69,42,678) = 109158
