So the greatest common factor 154,249 is 1.
Lets's calculate LCM of 690,440
2 | 690, 440 |
5 | 345, 220 |
69, 44 |
∴ So the LCM of the given numbers is 2 x 5 x 69 x 44 = 30360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30360
Therefore, the GCF of Fractions 154/690,249/440 is 1/30360
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 690,440 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(690,440) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(690,440) x common factors =10 x 1 = 10
LCM(690,440) = ( 690 × 440 ) / 10
LCM(690,440) = 303600 / 10
LCM(690,440) = 30360
