Video Summary

The problem is to find how many three-digit integers are divisible by 13. The first three-digit integer divisible by 13 is 104 (13 times 8), and the last is 988 (13 times 76). Therefore, the range of these integers is from 104 to 988. Calculating the number of these integers, we have 76 − 8 + 1, which equals 69. Thus, there are 69 positive three-digit integers divisible by 13.
