So the greatest common factor 428,210,578 is 2.
Lets's calculate LCM of 60,45,90
2 | 60, 45, 90 |
3 | 30, 45, 45 |
3 | 10, 15, 15 |
5 | 10, 5, 5 |
2, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 2 x 1 x 1 = 180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/180
Therefore, the GCF of Fractions 428/60,210/45,578/90 is 2/180
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 60,45,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(60,45,90) = 15
common factors(in case of two or more numbers have common factors) = 90
GCF(60,45,90) x common factors =15 x 90 = 1350
LCM(60,45,90) = ( 60 × 45 × 90 ) / 1350
LCM(60,45,90) = 243000 / 1350
LCM(60,45,90) = 180
