. prime number meaning

Best Answer

A number more than 1 with exactly factors, i.e. 1 and the number itself is described as a prime number. In different words, if a number cannot be divided into same groups, then it is a prime number. We can divide a number into groups with same numbers of items/elements only if it is able to be factorized as a product of numbers. For example,5 cannot be divided into groups of equal numbers. This is because 5 can only be factorized as follows:

5 x 1 = 5

5 × 7 = 5
