\(180=2^2.3^2.5\\ 234=2.13.3^2\)
ƯCLN ( 180,234)=\(2.3^2\)=18
ƯC(180,234)=Ư(18)={ 1,2,3,6,9,18}
a, chia hết cho 9 : \(801,108,810\)
b, chia hết cho 2 nhưng ko chia hết cho 5 : \(108,138,318,388,118\)
Ta có
\(39-4=35\) thì chia hết cho a
\(48-6=42\) thì chia hết cho a
⇒ a thuộc Ư(35,42)
\(35=5.7\\ 42=2.3.7\)
⇒ ƯCLN(35;42) là 7
⇒ ƯC(35;42) là Ư (7) = { 1,7}
Vậy a= 1,7
