What is the smallest composite number that is not divisible by 235 or 7?
4 is the smallest composite number and it is not divisible by the two given numbers.
How many prime numbers have squares between 100 and 300?
There are two prime numbers with squares between 100 and 300. These prime numbers are 11 and 13. (112 = 121 and 132 = 169.)
You are an odd number between 120 and 150 and is divisible by 3 5 7 or 9 who are you?
You could be 121.
Determine the number of integers between 1 to 250 that are divisible by any of the integer 3 or 5 or 7?
It would probably be easier to say that all numbers between 2 and 250 with the exception of the numbers 121, 143, 169 are divisible by the numbers 2,3,5, or 7. Explanation: One of the basic rules of math called the "Fundamental theorem of arithmetic" states that all numbers can be written as a product of prime numbers. 2, 3, 5, and 7 are the first four prime numbers. We also know that at least one of the numbers multiplied has to be less then 16. This is because the square root of 250 is about 15.81. If more then one of the numbers were larger then 16, then the result would be greater then 250. Example = 16*16 = 256. So now we know that all numbers between 2 and 250 are divisible by prime numbers that are less then 16. These numbers are "2,3,5,7,11,13." If you notice the first four numbers in that list are the numbers that you gave. This means that the only numbers between 2 and 250 that aren't divisible by 2, 3, 5, and 7 are the numbers (11*11), (11*13), and (13*13) or 121, 143, 169.
What are the square numbers between 101 and 200?
The are: 121 144 169 and 196
