A number which is divisible by only itself and 1 is called a Prime number. It means a prime number has only two factors.
Let us say n is a prime number then its factors are 1 and n.
So for any prime number we can easily write its factors because it has only two factors: 1 and the number itself.
Similarly we can write the factors of prime numbers from 1 to 100.
2: 1 and 2
3: 1 and 3
5: 1 and 5
7: 1 and 7
11: 1 and 11 & so on.
From the definition of prime number it is clear that writing down the factors of a prime number is not a difficult task because we don't need to do any calculation.
But for the prime numbers from 1 to 100 writing the factors is a tedious task as it involves nothing but writing 1 and the number itself.
