How many integers between 100 and 500 are divisible by 6 but not 8?
There are (500-100)/2 = 200 numbers divisible by 2 between 100 and 500 counting 100 but not 500. Of these (500-100)/8 = 50 are divisible by 8. So there are 150 numbers between 100 and 500 divisible by two but not by 8. By relative primeness exactly 50 out of these 150 are divisible by 3 and therefore these 50 are exactly the ones divisible by 6 but not by 8.
How many prime numbers are there between 50 and 70?
The prime numbers between 50 and 70 are: 53 59 61 67 Therefore, there are four prime numbers between 50 and 70.
What is the sum of the prime numbers coming immediately before and after 50?
The prime number that is closest to 50 and smaller than it is 47 (check it, 48 and 49 are divisible by other numbers than 1 and themselves). The prime number that is closest to 50 and is bigger than it is 53 (51 and 52 are divisible by other numbers than 1 and themselves). Therefore: 47+53=100 100 is the answer.
What numbers are divisible by 511?
An infinite number of numbers are divisible by 511
Are all even numbers divisible by 6?
Not all even numbers are divisible by 6. These numbers are not evenly divisible by 6: Any number smaller than 6. Any number not divisible by 3. If a number is divisible by both 2 and 3, it is divisible by 6.
Is 50 divisible by all numbers?
50 is divisible by 1, 2, 5, 10, 25 and 50 in the set of whole numbers. In the set of real numbers, 50 is divisible by any number and the answer will be a whole number only if it is divided by the 6 numbers mentioned above.
Is 50 divisible by 3?
No. 50 is divisible by these numbers: 1, 2, 5, 10, 25, 50.
Numbers divisible by 25 also divisible by 2?
Some numbers are divisible by 2 and Some are not.
What Natural numbers less than 200 that are divisible by 4 but not divisible by 3?

What numbers are divisible by 50 without remainders?
50 is divisable by 1,2,5.10,25,50
How many numbers between 10 and 50 are divisible by 2?
21 numbers - if you include the 10 and the 50.
Is 50 A factor?
It is of numbers evenly divisible by it like 100.
Which numbers from 1-50 are divisible by 10?
10, 20, 30, 40, 50
How many numbers in the first 200 natural numbers are divisible by 6 or 8?
50 of them.
Is it true that some numbers divisible by 5 are odd numbers?
50% of numbers divisible by 5 are even, the other 50% are odd. If the single's digit of a number is 5, then the number is divisible by 5 and odd. For example, 25. However, if the single's digit of a number is 0, then the number is divisible by 5 and even. For example, 20.
How many numbers between 1 to 50 are divisible by 3?
Counting up from 1, there is a number divisible by 3 every 3 numbers. Thus to find out how many numbers are divisible by 3, we just have to divide the number we're counting to by 3. In this case, the top number is 50, so do: 50/3 = 16 with two remainder. Because the numbers divisible by 3 come last in every set of 3 numbers, we can discard the remainder. Therefore there are 16 numbers between 1 and 50 that are divisible by 3.
How many whole numbers less than 50 are divisible by 5 or 7 but not both?
14. Assuming dealing with only counting numbers (ie integers greater than 0): Numbers divisible by 5 or 7 are their multiples. 50 ÷ 5 = 10 → last multiple of 5 less than 50 is 9 x 5 → 9 numbers less than 50 are divisible by 5 50 ÷ 7 = 71/7 → last multiple of 7 less than 50 is 7 x 7 → 7 numbers less than 50 are divisible by 7 Numbers divisible by both are those which are multiples of their lowest common multiple = 35 50 ÷ 35 = 115/35 → last multiple of 35 less than 50 is 1 x 35 → 1 number less than 50 is divisible by both 5 and 7 and needs to be removed from both the above counts. → (9 - 1) + (7 - 1) = 14 numbers less than 50 are divisible by 5 or 7 but not both. If there is no restriction on numbers being greater than 0, there are infinitely many numbers as it includes the infinite number of negative numbers which are all less than 50 and provide an infinite number of numbers divisible by 5 or 7 but not both.
