When an integer is multiplied by 17, the last three digits of the product are 123, so what is the smallest integer?

When an integer is multiplied by 17, the last three digits of the product are 123, so what is the smallest integer?

Do
i = i + 1
If Right(i * 17,3) = 123 Then:Print i :Exit Do
Loop
This is calculated by VB program, and the result is 419
I calculate by inference that if the mantissa is 3, then only 9 and 17 can be multiplied, that is to say, the last digit of this number is 9
So 17 * 9 = 153, that is to say, the last step of division calculation is 153, and the second digit is 2. If you want to subtract it and make it 5, then you can only subtract 7, and you have to borrow 1 from the front. When 17 is multiplied by 1, you can get the mantissa of 7, then the penultimate digit of this number is 1, and the penultimate step should be subtracting 17 quotient 1 from the remainder, and the mantissa is 2, then you can only fill in 3, and if you want to borrow 1, you can only fill in 3
Khan, it's too messy, you use the division method of primary school to calculate, push forward from the back!

The sum of three consecutive odd numbers is 123. What are the three odd numbers?

Let the middle number be x, then the two sides are x + 2, X-2
x-2+x+x+2=123
x=41
So the three are 39, 41 and 43 respectively

The number that is both odd and prime has______ ．

According to the definition of odd and prime numbers, there are 7 odd and prime numbers within 20: 3, 5, 7, 11, 13, 17 and 19. If the number is within 100, there will be more. Therefore, there is no scope for this question, so there are innumerable

An odd number is a two digit number. The sum of the numbers in each digit is 9. What is the possible number

45
sixty-three
twenty-seven
eighty-one

Of the three digits, the smallest odd number is______ The largest odd number is______ The smallest even number is______ The largest even number is______ ．

Among the three digit numbers, the smallest odd number is 101 and the largest odd number is 999; the smallest even number is 100 and the largest even number is 998

How many 7 digits are there, and the sum of the numbers is even

1000 00X---------999 999X
There are 900000 numbers in the upper 6 digits, and ABCDEF is arbitrarily selected,
Take the low order from 0 to 9, where the sum of 5 numbers is even
Therefore, a total of 900000 * 5 = 4500000 meet the requirements

Use 8650 four numbers to form the largest odd number and the smallest even number

The largest odd number is 8605, and the smallest even number is 5068

What is the largest odd number and what is the largest even number

The largest odd number is 9703 and the largest even number is 9730

Select 4 odd numbers and 2 even numbers from the 10 numbers of 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 to form 6-digit numbers without repetition

C5 4 * C5 2 * A6 6 - C5 4 * C5 1*A5 5
First select 6 numbers, no repeated arrangement, and then subtract the selected number which is zero and starts with zero
The answer is 5 * 10 * 720-5 * 5 * 120 = 33000

From 0,1,2 From the ten numbers, take three odd numbers and two even numbers to form a five digit number without repetition. How many are there in total
thank

There are 60 × 120 = 7200 cases when taking 3 odd numbers from 1 to 9 and 1 even number from 1 to 9. There are 40 cases when taking 3 odd numbers from 1 to 9 and 1 even number from 1 to 9
