It is the product, not the sum, of three consecutive integers that is divisible by 6. The three consecutive integers must be multiplied, not added.
For example, 2+3+4 = 9, which is not evenly divisible by 6.
If your first number is odd, then the statement works. Here's why:
The first number is odd, so it can be written as 2n+1 for some integer n.
The next two numbers are just 2n+2 and 2n+3.
Then the sum of the three numbers is:
(2n+1) + (2n+2) + (2n+3) = 6n + 6
which is obviously divisible by 6 regardless of the number you used for n.

The same is true for any number. Given two numbers, x and y, to make them multiples of 6 they can be written as 6x and 6y. According to the distributive property, their sum (6x + 6y) can also be written as 6(x + y). That means that whatever the sum of x + y is, it will also be a multiple of 6.
Think of it this way: Multiplication is multiple addition.
2 x 6 = 6 + 6
3 x 6 + 6 + 6 + 6
It doesn't matter how many sixes each number has. Adding them together will just create a longer string of sixes.
2 x 3 = 6
That means that 2 and 3 are factors of 6. Any multiple of 6 will still have at least one 2 and one 3 in it.
Try it out.
1 x 2 x 3
2 x 2 x 3
3 x 2 x 3
4 x 2 x 3
Of course, any multiple of 6 will be divisible by six.
Any multiple of 6 will have 3 as a factor, which means it will be divisible by three.
Any multiple of 6 will have 2 as a factor, which means it will be divisible by two.
By definition, any number that is divisible by two is even.
All multiples of 6 have 2 as a factor.
All numbers that have 2 as a factor are even.
It is not prime - you can divide it by 2 or 3; a Prime number can only be divided by itself and 1
6 has 2 as a factor. All multiples of 6 have 2 as a factor. Numbers that have 2 as a factor are even. Even numbers have even numbers in the ones place.
The prime factors of 2 are: Well, 2 has no prime factors because 2 is a prime number The prime factors of 6 are: 1, 2, 3, & 6
You can think of a factor as a number that divides another number with no remainder. For example, 3 is a factor of 6 since 3 goes into 6 two times with no remainder. Now if the factor is prime, then it is a prime factor. So in the example above, 3 is a prime factor. This is because the factor itself has only two factors, 1 and itself. 6 goes into itself also, but since 6 is not prime, it is not a prime factor. Now that you understand it, here is a more precise definition. A prime factor is a factor that is a prime number. In other words, one of the prime numbers that, when multiplied, give the original number.
643 dosen`t have a prime factorization because it`s already prime.
no because 6 is an even number and divisable by 2
Every even number, except 2, is not prime. example: 4, 6, 8, 10, and so on.
