Some positive numbers are divisible by 13, but not all of them.
To find the number of integers between 400 and 800 that are divisible by 13, we first need to find the smallest and largest multiples of 13 within this range. The smallest multiple of 13 greater than or equal to 400 is 403, and the largest multiple less than or equal to 800 is 793. To find the count of numbers divisible by 13 in this range, we calculate (793-403)/13 + 1 = 31. Therefore, there are 31 numbers between 400 and 800 that are divisible by 13.
The divisibility rule for 3 is as follows: If the sum of the digits of a number is divisible by 3 then the number is divisible by 3. For example, the number 21 is divisible by 3 since 2+1=3, and 3 is divisible by 3. The number 49 is not divisible by 3 since 4+9=13, and 13 is not divisible by 3.
The number must be divisible by 13 and by 11.
The smallest odd prime number is 3. The product of 13 and 3 is 39. 13 x 3 = 39

A number is divisible by 13 if it is a multiple of 13. In other words, 13 times a number results in a big number that is divisible by 13.
It is 11*13 = 143
13 and all its multiples are divisible by 13.

The number 70 is divisible by 13, but not evenly.
The greatest common factor is 13. Both 26 and 91 are divisible by 13. The greatest common factor cannot be larger than the smallest number, so the greatest common factor in this case is the smallest number - 13, since it is a factor of the other two numbers.
