No, 11 is a factor of 891.
1338 = 2x3x223 891 = 3x3x3x3x11 gcf = 3
No - the positive integer factors of 891 are: 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
3 x 3 x 3 x 3 x 11 = 891
As a product of its prime factors: 3*3*3*3*11 = 891
1 and 891 3 and 297 9 and 99 11 and 81 27 and 33
The factors are: 1, 3, 9, 11, 27, 33, 81, 99, 297, and 891. The prime factorization is: 34 x 11
You divide by one prime after another until you find a factor. Then you repeat the process with the quotient, starting with that factor.You divide by one prime after another until you find a factor.

No because it has more than two factors
(981) = 3 * (327)(327) = 3 * 109prime factors are 3*3*109 = 981
It's composite because you can divide it by three.
Yes. Any time three is a factor, it is a prime factor.
