The number 231 is divisible by 1, 3, 7, 11, 21, 33, 77, 231.
0.013
They are: 2+229 = 231
2 + 3 + 1 = 6, which is divisible by 3, so 231 is divisible by 3. Divide to get 231 = 77 Hard to miss that this is divisible by 7, so we get 231 = 3*7*11
I guess the only prime numbers that equal 231 are two and 229.
You can divide 231 by 1, 3, 7, 11, 21, 33, 77, and 231. These are the factors of 231.
The number 231 can be divided by 1, 3, 7, 11, 21, 33, 77, and 231. These numbers are factors of 231 because they can evenly divide 231 without leaving a remainder. Factors are numbers that can be multiplied together to get the original number, in this case, 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
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.
you right the numbers and divide
You have to add those two numbers then divide them by 2. The reason you divide by 2 is because they're two numbers.
231
You divide by the number of numbers - if you want the mean of three numbers you divide by 3, if you want the mean of a hundred numbers you divide by 100.
