So the greatest common factor 407,605,770 is 11.
Lets's calculate LCM of 40,20,411
2 | 40, 20, 411 |
2 | 20, 10, 411 |
5 | 5, 10, 411 |
1, 2, 411 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 1 x 2 x 411 = 16440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/16440
Therefore, the GCF of Fractions 407/40,605/20,770/411 is 11/16440
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 40,20,411 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,20,411) = 1
common factors(in case of two or more numbers have common factors) = 20
GCF(40,20,411) x common factors =1 x 20 = 20
LCM(40,20,411) = ( 40 × 20 × 411 ) / 20
LCM(40,20,411) = 328800 / 20
LCM(40,20,411) = 16440
