When an integer is multiplied by 13, the last three digits of the product are 123. What is the minimum number of such an integer?

Integer is the smallest, we can know that the product is also the smallest; so the product is at least four digits, from the thousand is 1, we can know from the discussion: 123 △ 13 ≈ 9.46 is a decimal; 1123 △ 13 ≈ 86.38 is a decimal; 2123 △ 13 ≈ 163.31 is a decimal; 3123 △ 13 ≈ 240.23 is a decimal; 4123 △ 13 ≈ 317.15 is a decimal; 5123 △ 13 ≈ 394.08 is a decimal; 6123 △ 13 = 471; 471 is an integer; answer: such a minimum The integer is 471

Among the unrepeated three digit numbers 0, 1, 2, 3, 4, 5 and 6, even numbers have______ One

There are two types of even numbers without repetition, which are composed of any three of the seven numbers 0, 1, 2, 3, 4, 5, 6. ① when the last digit is 0, such three digits have A62 = 30. ② when the last digit is not 0, choose one of the remaining three even numbers to put in the first place, and then choose one of the remaining five non-zero numbers to put in the first place, and then choose one from the remaining five non-zero numbers to put in the first place Take one of the numbers and put it in the tenth place. From this, we can see that the even numbers that meet the conditions are: A31 × A51 × A51 = 75. To sum up, there are 30 + 75 = 105 three digit numbers. Answer: there are 105 even numbers among the three digit numbers without repetition. So the answer is: 105
