So the greatest common factor 19,66,643 is 1.
Lets's calculate LCM of 111,279,567
3 | 111, 279, 567 |
3 | 37, 93, 189 |
37, 31, 63 |
∴ So the LCM of the given numbers is 3 x 3 x 37 x 31 x 63 = 650349
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/650349
Therefore, the GCF of Fractions 19/111,66/279,643/567 is 1/650349
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 111,279,567 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(111,279,567) = 3
common factors(in case of two or more numbers have common factors) = 9
GCF(111,279,567) x common factors =3 x 9 = 27
LCM(111,279,567) = ( 111 × 279 × 567 ) / 27
LCM(111,279,567) = 17559423 / 27
LCM(111,279,567) = 650349
