# School

Headteacher think whether the distribution of pupils in race in groups of 4,5,6,9 or 10. How many pupils must have at least school at possible options?

Result

x =  180

#### Solution:

$4=2^2 \ \\ 5 \ ... \ prime number \ \\ 6=2 \cdot 3 \ \\ 9=3^2 \ \\ 10=2 \cdot 5 \ \\ LCM(4, 5, 6, 9, 10)=2^2 \cdot 3^2 \cdot 5=180 \ \\ \ \\ x=LCM(4,5,6,9,10)=180$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
