So the greatest common factor 603,140,765 is 1.
Lets's calculate LCM of 39,72,66
2 | 39, 72, 66 |
3 | 39, 36, 33 |
13, 12, 11 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 12 x 11 = 10296
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10296
Therefore, the GCF of Fractions 603/39,140/72,765/66 is 1/10296
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 39,72,66 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,72,66) = 3
common factors(in case of two or more numbers have common factors) = 6
GCF(39,72,66) x common factors =3 x 6 = 18
LCM(39,72,66) = ( 39 × 72 × 66 ) / 18
LCM(39,72,66) = 185328 / 18
LCM(39,72,66) = 10296
