Prime numbers have no factors. They are numbers that are divisible by only themselves and the number 1. Therefore, of the set {1, 2, 3, 4, 5, 6, 7, 8, 9}, the following numbers are primes: {2, 3, 5, 7}

Which is the lowest prime number 0 1 2 3 5?
1 is the lowest prime number. Extra: 2 is the ONLY even prime number.
How do you tell if a number is prime?
A prime number cannot be divided by any other number except for 1 and itself and result in a whole number (positive integer). For example, 3 is a prime number. You can divide 3 by one or three and get a whole number. If you divide three by any other positive integer (for example 2) you get a fraction (or a decimal). 10 on the other hand is NOT a prime number. 10 is divisible by 1 and 10, but it is also divisible by 5 and 2: 10/2 = 5 10/5 = 2 If a number cannot be divided by any whole number other than itself or 1, with a whole number as the result the number is prime. 1/1=1 prime 2/2=1, 2/1=2 prime 3/3=1, 3/1=3 prime 4/4=1, 4/1=4, but 4 can also be divided by 2 with a whole number as the result 4/2=2, so it is not prime. Just think if are there any two numbers that can be multiplied together to get the number other than itself and 1. If there are, it is not prime. For example 25 is not prime bexuse 5x5=25. 13 is prime because no whole numbers, other than 13 and 1, can be multiplied together to get 13. 1-prime 2-prime 3-prime 4-not prime (2x2=4) 5-prime 6-not prime (2x3=6) 7-prime 8-not prime (2x4=8) 9-not prime (3x3=9) 10-not prime (2x5=10) 11-prime 12-not prime (3x4=12, 2x6=12)
What is the reciprocal of the smallest odd prime number?
1/2
Why do prime numbers have a remainder of 1 or 5 when divided by 6?
If the number has a remainder of 2 or 4 when divided by 6, it is an even number, so it is not prime number. 6n + 2 = 2 (3n + 1), so it is divisible by 2. 6n + 4 = 2 (3n + 2), so it is divisible by 2. If the number has a remainder of 3 when divided by 6, it is divisible by 3, so it is not a prime number. 6n + 3 = 3 (2n + 1), so it is divisible by 3. However, there are two prime numbers that do not have a remainder of 1 or 5 when divided by 6 : 2 and 3

What are the prime numbers between 1 to 10?
2 3 5 7 (the number 1 is NOT a prime number).
Which is the lowest prime number 0 1 2 3 5?
1 is the lowest prime number. Extra: 2 is the ONLY even prime number.
What is the smallest number which is exactly divisible by all the numbers from 1 12?
27, 720 1 is prime 2 is prime 3 is prime 4 = 2^2 (number must have 2 factors of 2) 5 is prime 6 = 2*3 (number must have at least 1 factor of three and one factor of 2) 7 is prime 8 = 2^3 9 = 3^2 10 = 5*2 11 = prime 12 = 2*2*3 2*2*2*3*3*5*7*11 = 27720 * * * * * 1 is not a prime (nor is it a composite number). The characteristic of prime or composite is defined for integers greater than 1.
Is there an Infinate number of prime numbers?
The number or prime numbers in infinite. Prime numbers can only be divided by 1 and the prime number itself. If you multiply all known prime numbers (you must not leave out any of them) and add 1 to the product the result is another prime number. E.g. 2 * 3 + 1 = 7 (prime) 2 * 3 * 5 + 1 = 31 (prime) 2 * 3 * 5 * 7 + 1 = 211 (prime) ... infinity
Which number is a prime number 4 10 or 3?
A prime number is a number that is divisible only by 1 and itself. It has no other factors. The factors of 3 are 1 and 3. It can be factored only as 1 x 3. The factors of 4 are 1, 2, and 4. It can be factored as either 1 x 4 or 2 x 2. The factors of 10 are 1, 2, 5, and 10. it can be factored as either 1 x 10 or 2 x 5. Therefore, 3 is the prime number.
What is the prime numbers in 1 2 3 6?
A prime number has 2 factors; 1 and itself. 0 and 1 are neither prime nor composite, so the prime numbers are 2 and 3.
