Lets's calculate LCM of 388,989,438
2 | 388, 989, 438 |
194, 989, 219 |
∴ So the LCM of the given numbers is 2 x 194 x 989 x 219 = 84037308
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/84037308
Therefore, the GCF of Fractions 727/388,492/989,690/438 is 1/84037308
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 388,989,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(388,989,438) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(388,989,438) x common factors =1 x 2 = 2
LCM(388,989,438) = ( 388 × 989 × 438 ) / 2
LCM(388,989,438) = 168074616 / 2
LCM(388,989,438) = 84037308
