If F is a 4- digit number, divisible by 9,10 and 13 then the smallest value of F is.........
If \(2a456b\) is divisible by 2,3,5 and 9 then a+b=.........
Ta có : \(\overline{2a456b}⋮2,3,5,9\) Mà : \(\overline{2a456b}⋮2,5\Rightarrow b=0\)
Mà : \(\overline{2a4560}⋮9\)
\(\Rightarrow2+a+4+5+6+0⋮9\)
\(\Rightarrow a+17⋮9\)
\(\Rightarrow\left(a+8\right)+9⋮9\)
Vì : \(9⋮9\Rightarrow a+8⋮9\)
Mà : a + 8 là chữ số .
\(\Rightarrow a+8=9\Rightarrow a=9-8\Rightarrow a=1\)
Vì : a = 1 và b = 0 => a + b = 1 + 0 = 1
Vậy a + b = 1
