Prime Factorization
Prime factorization is finding out all the prime numbers which when multiplied result in the original number.
A factor tree is a tool that helps us to break down the given number into its prime factors. In this method we factorize the given number and we only stop when we can’t find factors any more.
Example 1: Find Prime Factor of 108.

News report about the dangers faced by fishes in our river and Seas:
The fishes and other lives at sea and rivers face numerous dangers from humans. Many trawlers do not limit themselves near the shores and use their huge fishing nets to catch large quantities.
By doing so, the population of fishes and other lives at the river and sea reduces incredibly. It in turn results in the unemployment of conventional fishermen. Also, the plastics disposed of ineffectively by humans put the aqua ecosystem to danger.

Prime numbers are the positive integers having only two factors, 1 and the integer itself. For example, factors of 6 are 1,2,3 and 6, which are four factors in total. But factors of 7 are only 1 and 7, totally two. Hence, 7 is a prime number but 6 is not, instead it is a composite number. But always remember that 1 is neither prime nor composite.

Consider a set of two numbers, if they have no positive integer that can divide both, other than 1, the pair of numbers is co-prime.
Example 1: 21 and 22
For 21 and 22:
- The factors of 21 are 1, 3, 7, and 21.
- The factors of 22 are 1, 2, 11, and 22.
Here 21 and 22 have only one common factor that is 1. Hence, their HCF is 1 and are co-prime.

Two prime numbers are called twin primes if there is present only one composite number between them. Or we can also say two prime numbers whose difference is two are called twin primes. For example, (3,5) are twin primes, since the difference between the two numbers 5 – 3 = 2. The alternative names, given to twin primes are prime twin or prime pair.
