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.
There are 24.
50 of them if you count 300.
Oh, dude, let me break it down for you. So, we start at 21 because it's the first number between 20 and 50 that's divisible by 3, and then we just keep adding 3 until we hit 48. So, that gives us 10 numbers in total. Easy peasy, right?
Using the tn formula, t1=56, the last number, tn=497, and d=7. Therefore, 497=56+(n-1)7. 448=7n, and n=64. So there are 64 numbers between 50 and 500 that are divisible by 7.
There are three numbers between 10 and 50 which are divisible by both 3 and 5. All numbers that are multiples of 3 and 5 are the multiples of the lowest common multiples (lcm) of 3 and 5 which is 15. The multiples of 15 between 10 and 50 are {15, 30 and 45}, thus there are 3 numbers.
there are 17 divisible by 3 between 50 to 100 , 51,54,57,60,63,66,69,72,75,78,81,84,87,90,93,96,99
21 numbers - if you include the 10 and the 50.
There are 24.

50 of them.
5
24. 25 if you include 50.
16, excluding 0.
50 of them if you count 300.
Exactly 50
The prime numbers between 50 and 70 are: 53 59 61 67 Therefore, there are four prime numbers between 50 and 70.
for 2 its 50 for 4 its 25
