The factors of 231 are:
1, 3, 7, 11, 21, 33, 77 and 231
231/34
231 written in binary numbers is 11100111
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
3 x 7 x 11 = 231
76 + 77 + 78 three numbers in a row
To find numbers that multiply to give you 231, you can factorize 231 and look for its prime factors. 231 = 3 * 7 * 11 So, the numbers you can multiply to get 231 are 3, 7, and 11.
1, 3, 7, 11, 21, 33, 77, 231
The three prime numbers that go into 231 are 3, 7 and 11.231 = 3 x 7 x 11
231/34
They are: 2+229 = 231
It is: 3*7*11 = 231
I guess the only prime numbers that equal 231 are two and 229.
As a product of its prime numbers: 3*7*11 = 231
3 * 7 * 11 = 231
They are: 3*7*14 = 231
200 + 30 + 1 = 231 3 x 7 x 11 = 231
They are: 3*7*11 = 231
