I guess the only prime numbers that equal 231 are two and 229.

3 times 7 times 11 equals 231.

231 is equal to 77 times 3. So the prime factors of 231 are 3, 7 and 11.

3 * 7 * 11 = 231

231 = 3 x 7 x 11

3 x 7 x 11 = 231

3 x 7 x 11 = 231

As a product of its prime numbers: 3*7*11 = 231

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

They are: 2+229 = 231

It is: 3*7*11 = 231

The prime factorization of 231 = 3 x 7 x 11
