The prime numbers from 1 - 20 are 2, 3, 5, 7, 11, 13, 17, and 19.
2, 3, 5, 7, 11, 13, 17, 19 ARE prime numbers! 1, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20 are NOT prime numbers!
It is 75.
To determine the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888, we can use the Prime Number Theorem. This theorem states that the density of prime numbers around a large number n is approximately 1/ln(n). Therefore, the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888 can be estimated by dividing ln(8888888888888888888888888888888888888888888888) by ln(2), which gives approximately 1.33 x 10^27 prime numbers.
NO. There are more prime numbers between 1 and 100 than the prime numbers between 101 and 200.number of prime numbers between 1 and 100 = 25number of prime numbers between 101 and 200 = 20
These are the prime numbers 1-20 2,3,5,7,11,13,17,19
2/5 of the numbers from 1 to 20 are prime numbers
Prime numbers are numbers that can only be divided by one and itself. The answer is 2,3,5,7,11,13,17,19. 1 is not prime nor composite.
The prime numbers between 1 and 20 are 2, 3, 5, 7, 11, 13, 17, and 19.
There are eight prime numbers from 1 to 20: 2 3 5 7 11 13 17 19
The prime numbers from 1 - 20 are 2, 3, 5, 7, 11, 13, 17, and 19.
There are 8 prime numbers between 1 and 20. The numbers are 2, 3, 5, 7, 11, 13, 17, and 19.
Prime numbers only have factors of 1 and themselves: 23, 29
The Prime Numbers in the 20's are 23 and 29 because they are only divisible by 1 and the number itself.
There are 8 out of 20 numbers that are prime, so 8/20, or 2/5.
The prime numbers from 1 to 20 are 2, 3, 5, 7, 11, 13, 17, and 19. The original answer incorrectly included 1, 9, and 15.
no, 20 is even; therefore it is a multiple of 2.
