## How to find the Factors of 18

**18**is a composite number.-
Prime factorization:
**18**= 2x3x3, which can be written**18**= 2^{1}x3^{2} - The exponents in the prime factorization are 1 and 2.
Adding one to each exponent and multiplying we get
(1 + 1)(2 + 1) = 2x3 = 6.
Therefore
**18**has exactly**6**factors. - The factors of
**18**are: 1, 2, 3, 6, 9 and 18 - Factor pairs of
**18**are: 1x18, 2x9 and 3x6 -
**18**has at least one exponent greater than 1 in its prime factorization so**√18**can be simplified. Taking this into account, we get**√18**= 3x√2
