231 is NOT a prime number. It is divisible by 3, 7 and 11.
They are: 3*7*11 = 231
231 = 3 x 7 x 11
A fundamental theorem in mathematics is that of unique factorisation. Any number can have only one prime factorisation. 231 = 3*7*11
13 is the greatest prime that needs to be checked to determine if 231 is a prime.

231 is prime.
231 = 3 x 7 x 11
To determine factors of a number it is necessary to divide the number by prime numbers of increasing value. If there is no remainder then the prime number is a factor. The square root of 231 is approximately 15 so it is necessary to divide by all the prime numbers up to 13 (15 is not a prime number). 231 ÷ 2 leaves a remainder of 1 231 ÷ 3 divides exactly 77 times (which is 7 x 11 - both are prime numbers) 231 ÷ 5 leaves a remainder of 1 231 ÷ 7 divides exactly 33 times (which is 3 x 11 - both are prime numbers) 231 ÷ 11 divides exactly 21 times (which is 3 x 7 - both are prime numbers) 231 ÷ 13 leaves a remainder of 10 If we multiply together the three numbers that are shown to be factors 3 x 7 x 11 = 231 this confirms that there are no other factors of 231 except 1 and 231 itself. This last condition is true for every positive integer. 231 is divisible by 1, 3, 7, 11 and 231

The 8 factors of 231 are 1, 3, 7, 11, 21, 33, 77, and 231. The prime factorization of 231 is 231 = 3 * 7 * 11. The prime factors of 231 are 3, 7 and 11.
prime factorization of 231
231 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 have a different name.
It is: 3711 = 231
13 is the greatest prime that needs to be checked to determine if 231 is a prime.
