WebDec 18, 2014 · 35. Primes are important because the security of many encryption algorithms are based on the fact that it is very fast to multiply two large prime numbers and get the result, while it is extremely computer-intensive to do the reverse. When you have a number which you know is the product of two primes, finding these two prime numbers is very hard. WebPrime Number. Step-by-step explanation: Prime numbers are numbers that have only 2 factors: 1 and themselves. For example, the first 5 prime numbers are 2, 3, 5, 7, and 11. By contrast, numbers with more than 2 factors are call composite numbers. A number with only two factors is called a prime number.
