A Prime number has exactly two factors: 1 and the number itself.
yes you are supposed to circle the prime#s and divide the composite
how am i supposed to kno do u think i am like magic or something ????
If it is unknown, how are we supposed to know it? There must be a least unknown prime, so the next prime below that must (?) be known, sap pk. The next prime, pk+1 , must be the least unknown prime - so what is it, approximately?
Euclid (c. 300 BC) was one of the first to prove that there are infinitely many prime numbers. His proof was essentially to assume that there were a finite number of prime numbers, and arrive at a contradiction. Thus, there must be infinitely many prime numbers. Specifically, he supposed that if there were a finite number of prime numbers, then if one were to multiply all those prime numbers together and add 1, it would result in a number that was not divisible by any of the (finite number of) prime numbers, thus would itself be a prime number larger than the largest prime number in the assumed list - a contradiction.
You is called a prime number!You is called a prime number!You is called a prime number!You is called a prime number!
7 is a prime number!
109 is a prime number.
167 is a prime number.
A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.
101 is a prime number. The only factor of 101 is itself and 1.prime
37 is an odd prime number
