The 15 factors of 324 are 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, and 324.Note: There are an odd number of factors because 324 is a square number (18 * 18).The factor pairs of 324 are 1 * 324, 2 * 162, 3 * 108, 4 * 81, 6 * 54, 9 * 36, 12 * 27, and 18 * 18.Prime factorization:324 = 2 * 2 * 3 * 3 * 3 * 3

The factors of 81 are 1, 3, 9, 27, and 81. The factor pairs of 81 are 1 x 81, 3 x 27, and 9 x 9. The proper factors of 81 are 1, 3, 9, and 27, or if the definition you are using excludes 1, they are 3, 9, and 27. The prime factors of 81 are 3, 3, 3, and 3. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed. The distinct prime factor of 81 is 3. The prime factorization of 81 is 3 x 3 x 3 x 3 or in exponential form 34. 81 = 3*3*3*3 or 3^4.

No. 81=9*9=3*27=1*81 81 has 5 factors and is a square number. 36=6*6=3*12=1*36=2*18=4*9 36 has 9 factors and is a square number. This doesn't mean that no square numbers have exactly 3 factors though, because: 9=3*3=1*9 9 has 3 factors and is a square number. 4=2*2=1*4 4 has 3 factors and is a square number. All square numbers have an odd number of factors though (because they have a whole number which multiplies by itself to get the number). Factors are whole numbers only, and not decimals. Hope this helps :)
