How many 10 digit prime numbers are there?
340,819,138
The Prime Number Theorem asserts that for x sufficiently large (and 10-digits is not too bad), we have the following approximation. It follows that π(9999999999) ≈ 434,294,481 and π(2002000000) ≈ 93,475,343, which means that there are roughly 340,819,138 10-digit prime phone numbers.
How many prime numbers are there total?
What are the prime numbers? There are 8 prime numbers under 20: 2, 3, 5, 7, 11, 13, 17 and 19. The first 10 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29. There are 25 prime numbers between 1 and 100.

How many 5 digit prime numbers have 6 digits?
999983 is the 78498th prime number. So there are 78498–9593+1 = 68906 prime numbers with 6 digits. How many five digit numbers are even? The number of even numbered numbers is 45000.
What is a prime number with no divisors?
A prime number is a natural number greater than 1 that has no positive integer divisors other than 1 and itself. For example, 5 is a prime number because it has no positive divisors other than 1 and 5.
What is the difference between 1 and 9 as a prime number?
A prime number is a number which has two factors: 1 and itself. So if you add the numbers 1,3 and 5, it gives you 9. This means any number made from the digits 1, 3 and 5 is divisible by 3. Therefore, no number made from the combination of all of the digits 1, 3, & 5 is prime. The difference between the two numbers is 1/9 of their sum.
What is the difference between prime numbers and composite numbers?
Prime Numbers. In contrast to prime numbers, a composite number is a positive integer greater than 1 that has more than two positive divisors. For example, 4 is a composite number because it has three positive divisors: 1, 2, and 4. All positive integers greater than 1 are either prime or composite.
