Division of numbers

Division of numbers:

1. If a and B can be divisible by C, their sum and difference can also be divisible by C.

2. If the accumulation ability of B and C is divided into A, both B and C can divide.

3. If B and C can divide a, and B and C are mutually compatible, the accumulation of B and C can divide.

4. If C can divide B and B can divide a, c can divide.

5. A continuous natural number must have a number that can be divisible by.

 

Number division features:

Features of a number that can be divisible by two: the number of digits is an integer of 0, 2, 4, 6, and 8.

Features of the number that can be divided by 5: The number of digits is an integer of 0 and 5.

Features of a number that can be divisible by 3 (9): numbers on each digit and integers that can be divisible by 3 (9.

Features of a number that can be divisible by 4 (25): the integer whose last two digits can be divisible by 4 (25.

A feature of the number that can be divisible by 8 (125): the integer whose last three digits can be divisible by 8 (125.

The feature of the number that can be divisible by 11: The difference (greatly reduced) between the sum of the numbers in the odd digits of this integer and the sum of the numbers in the even bits is a multiple of 11.

The feature of a number that can be divisible by 7 (11 or 13): the difference between the last three digits of an integer and the number of the last three digits before the last three digits (greatly reduced) can be divisible by 7 (11 or 13.
