. What do you mean by Prime number?
Any whole number greater than one that is divisible only by one and itself is defined as a prime number.
In another words, if a number cannot be divided into equal groups, then it is a prime number. We can only divide a number into groups with equal numbers of items/elements if it can be factorized as a product of two numbers. For example, 5 cannot be divided into groups of equal numbers.
5 can only be factorized as mention below:
5 × 1 = 5
1 x 5 = 5
