We found the factors 923,6438 . The biggest common factor number is the GCF number.
So the greatest common factor 923,6438 is 1.
Lets's calculate LCM of 840,580
2 | 840, 580 |
2 | 420, 290 |
5 | 210, 145 |
42, 29 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 42 x 29 = 24360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/24360
Therefore, the GCF of Fractions 923/840,6438/580 is 1/24360
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 840,580 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(840,580) = 20
common factors(in case of two or more numbers have common factors) = 1
GCF(840,580) x common factors =20 x 1 = 20
LCM(840,580) = ( 840 × 580 ) / 20
LCM(840,580) = 487200 / 20
LCM(840,580) = 24360
