Three is actually looking at how many circles there are in the first four numbers

Take another natural number from one natural number, the incomplete quotient is 8, the remainder is 16, and the sum of divisor, divisor, quotient and remainder is 463

If the divisor is x, the divisor is 8x + 16
So 8x + 16 + X + 8 + 16 = 463
9x + 40 = 463
9x = 423
x = 47
A: the divisor is 47

The quotient of two natural numbers is 39. The remainder is 4. The sum of divisor, divisor, quotient and remainder is 247. What is the divisor?

The divisor is X
So the divisor is 39x + 4
So x + 39x + 4 + 39 + 4 = 247
X=5

The sum of the divisor, divisor, quotient and remainder is 629, and the divisor is______ ．

Let the divisor be x, then: (47x + 3) + X + 47 + 3 = 629, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 48x + 53 = 629, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 48x = 576, & nbsp

The sum of three continuous natural numbers is 96. What are the three natural numbers?

31 32 33

1. Among the 1997 natural numbers 1,2,3 ·· 1996, 1997, how many natural numbers contain the number 1?
2. 111 ··· 1} 100 1s are multiplied by 999 ··· 9} 100 9s. How many numbers are odd in the product?
3. How many zeros are there at the end of the product of 1 × 2 × 3 ··× 49 × 50?
Thanks for zhangweizmy's answer. But your method can only be estimated. For example, the example 30! In your blog, do you think it should be 7 or 8? The two numbers are close together. You can only guess by luck

There are 998 after 1000
From 200 to 999, there are 18 for every 100, a total of 144
There are 18 in 99,
There are 200 from 100 to 199
It's 1360ge

If the sum of the numbers on each bit of a natural number n is 1996, what is the minimum number

The minimum number of digits must be as few as possible, so divide 1996 by 9, the quotient is 221 and the minimum number is 79999 99999 (221 9)
