Ta gọi số cần tìm là a
Ta có:a:15 dư 2 ---> a-2 chia hết(dấu) cho 15
a:32 dư 2----> a-2 chia hết cho 32
a:75 dư 2----->a-2 chia hết cho 75
Suy ra a thuộc BC{15,32,75}
Ta có: 15 = 3.5
32=25.1
75=3.52
BCNN(15,32,75)=3.25.52=1200
Suy ra a-5 thuộc B(1200)
Suy ra a-5 thuộc(1200 , 2400, 3600,4800,...)
Suy ra a thuộc(1202,2402,3602,4802,...)
Do a nhỏ nhất nên a =1202
Vậy số đó là:1202
