A natural number (all numbers without decimal places) are considered to be divisible by another natural number, when the result of the division is another natural number (i.e. no rest or decimal places arising). Since 162/6 = 27 162 meets the requirements to be divisible by 6. All numbers divisible by 2 and 3 are also divisible by 6.
There are 39 natural numbers between 1,000 and 1,500, inclusive, that are divisible by 13.
