Problem Statements: Is 23 a Prime Number? Yes Is 23 a Composite Number? No Square Root of 23 4. No Cube Root of 23 2. No Multiples of 23 23, 46, 69, 92, , , , , , Is 23 an Odd Number? Yes Is 23 an Even Number? No Fun Facts: A pair of prime numbers X and Y are said to be twin prime numbers if the absolute difference between them is 2.

Example - , are twin prime numbers. Numbers X and Y are said to be coprime if they have only one common factor that is 1. Prime factorization means expressing a number as the product of its prime factors. In the factorization method, consider the numbers, 1 and 23 as factors of It has only two factors, i.

So the prime factorization of the number 23 is The pair of numbers which gives 23 when multiplied are the factors of 23 in pairs. T he following are the positive and negative factor pairs of 1, 23 and -1, Example 1: Johnson has 23 lampshades to be packed in boxes.

Each box should contain an equal number of lampshades. Each box should contain an equal number of lamps, and the number 23 does not have any factors other than 1 and itself. Since, the factors of 23 are 1, 23 and factors of 18 are 1, 2, 3, 6, 9, Hence, 23 and 18 have only one common factor which is 1.

Therefore, 23 and 18 are co-prime. The factors of 23 are 1, 23 and the factors of 20 are 1, 2, 4, 5, 10, More modern techniques include the sieve of Atkin, probabilistic algorithms, and the cyclotomic AKS test.
