Answer 2

13, 43 and 23 are the prime numbers.

• The positive integers that can divide a number evenly are known as factors in mathematics. Let's say we multiply two numbers to produce a result. The product's factors are the number that is multiplied. Each number has a self-referential element. There are several examples of factors in everyday life, such putting candies in a box, arranging numbers in a certain pattern, giving chocolates to kids, etc. We must apply the multiplication or division method in order to determine a number's factors.
• The numbers that can divide a number exactly are called factors. There is therefore no residual after division. The numbers you multiply together to obtain another number are  called factors. A factor is therefore another number's divisor.

Here, according to the given information, we are given that,

13,27,81,21,43,48,23,39,45.

Here, 13, 43 and 23 are the prime numbers as they have only 1 and itself as the factors.

Hence, 13, 43 and 23 are the prime numbers.
