Lets's calculate LCM of 999,810,665
3 | 999, 810, 665 |
3 | 333, 270, 665 |
3 | 111, 90, 665 |
5 | 37, 30, 665 |
37, 6, 133 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 5 x 37 x 6 x 133 = 3986010
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3986010
Therefore, the GCF of Fractions 45/999,40/810,249/665 is 1/3986010
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 999,810,665 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(999,810,665) = 1
common factors(in case of two or more numbers have common factors) = 135
GCF(999,810,665) x common factors =1 x 135 = 135
LCM(999,810,665) = ( 999 × 810 × 665 ) / 135
LCM(999,810,665) = 538111350 / 135
LCM(999,810,665) = 3986010
