How many positive integers less than 20 are divisible by either 2 or 3?
(b) How many positive integers not bigger than 20 are divisible by either 2 or 3? Solution: There are ⌊20/2⌋ = 10 that are divisible by 2, and ⌊20/3⌋ = 6 that are divisible by 3. But there are also ⌊20/6⌋ = 3 that are divisible by both 2 and 3, so the total is 10 + 6 − 3 = 13.

You can designate a minimum value to generate multiples greater than a number. For example, to find 100 multiples of 36 that are greater than 1000 you will get: 1008, 1044, 1080, 1116, 1152, 1188, 1224, 1260, 1296, 1332, 1368, 1404, etc. Here is a list of the first 20 multiples of the integers 1 through 20.
How many positive integers are divisible by 1 or itself?
In all the positive integers given above, all are either divisible by 1 or itself, i.e. precisely two positive integers. The smallest prime number defined by modern mathematicians is 2. To be prime, a number must be divisible only by 1 and the number itself which is fulfilled by the number 2.
Why 18+4 and 3+16 are not considered as positive integers?
Since we are looking for positive integers· less than 20, that are equal to the sum of a positive multiple of 3 and a positive multiple of 4, Why 18+4 and 3+16 are not considered? The problem do not mention that the sum of the multiples has to be less than 20. Which means that the numbers MUST be under 20.
