a, Để 7a5b1 chia hết cho 3

ta có: 7 + a + 5 + b + 1 chia hết cho 3

=> 13 + a + b chia hết cho 3

mà a - b = 4 => a + b ≥ 4

=> a + b ϵ { 5; 8 }

+) Nếu a + b = 5 mà a - b = 4

=> a + a - 4 = 5 ( b = a - 4 )

=> 2a = 9

=> a = 4,5 ( vì a là chữ số nên loại )

+) Nếu a + b = 8 mà a - b = 4

=> a + a - 4 = 8

=> 2a = 12

=> a = 6

=> 6 - b = 4

=> b = 2

Vậy a = 6, b = 2. Số cần tìm là 765321
