So the greatest common factor 412,405 is 1.
Lets's calculate LCM of 276,120
2 | 276, 120 |
2 | 138, 60 |
3 | 69, 30 |
23, 10 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 23 x 10 = 2760
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2760
Therefore, the GCF of Fractions 412/276,405/120 is 1/2760
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 276,120 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(276,120) = 12
common factors(in case of two or more numbers have common factors) = 1
GCF(276,120) x common factors =12 x 1 = 12
LCM(276,120) = ( 276 × 120 ) / 12
LCM(276,120) = 33120 / 12
LCM(276,120) = 2760
