There are 6,750 such numbers.
Once with a remainder of three or 1.5 times
Divide it by each prime number which does not have remainder.
Nobody knows for sure how many robins there are in a world. These birds are not endangered and there is nobody counting their exact numbers. Estimates are that the number of robins is in the millions.
Eight: 45, 50, 55, 60, 65, 70, 75 and 80.
There are 16. Counting numbers are numbers that can be used to count whole amounts of things: 1, 2, 3, etc. (no fractions) You can divide 120 by 1 and get an answer of 120 with no remainder. Likewise you can divide 120 by 120 and get an answer of 1 with no remainder. Most of the time the answers will be in pairs. Here are all of the counting numbers that leave no remainder when divided into 120: 1, 120, 2, 60, 3, 40, 4, 30, 5, 24, 6, 20, 8, 15, 10, 12.
Amongst counting numbers (positive integers) only 4.
Sixteen.
55
1, 2, 4, 7, 14, and 28 are the numbers that match this description. Therefore, six numbers divide into it evenly.
Only one: 59.
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.
1, 2, 3, 5, 6, 10, 15 and 30.
Four: 1 5 31 and 155.
The question is asking how many integers go into 36 with no remainders.2,3,4,6,9,12,36
87 is one of infinitely many numbers that meet these requirements.
No- not exactly. Negative integers are not counting numbers. Positive integers are identified with counting numbers. Many authors like to start with zero as a counting number.
