A and b are numbers where a equals b plus 2 the sum of a and v is equal to the product of a and b show that a and b are not integers?

Basically, you have the following linear equation system:
a = b + 2
a + b = a * b (I assume "v" is a typo for "b").
Substituting (b+2) for a in the second equation, we get:
2b+2 = b(b+2) = b^2+2b
Subtracting (2b) from both sides, we get:
2 = b^2
and we can conclude that:
b = sqrt(2)
which is not an integer (in fact, it is not even rational).
And it is pretty easy to prove that sqrt(2) is not an integer, if needed.

What is the possibility for a given pair of numbers to be less than or equal to their product?
Depending on what numbers are you picking from: {Integers, Whole Numbers, Natural numbers, All real numbers} will affect the probability.
What is the highest possible product of 3 numbers that sum to 20?
If the numbers are positive integers then the maximum product is usually obtained when the three numbers are equal but this cannot apply in this case. However, the three numbers that are almost equal are 7,7 and 6. The maximum product is, 7 x 7 x 6 = 294.
When is the product of two nonzero integers less than or equal of the two factors?
When one of the numbers is positive and the other is negative.
What 2 numbers sum equal 10 and their product equals 22?

Why is the least common multiple of 2 prime numbers their product?
Because prime numbers don't have any common prime factors. Their GCF is 1. Since the product of the GCF and LCM of a pair of numbers equals the product of the numbers, the LCM has to be equal to the product.
How can you use greatest common factor x least common multiple equals A x B?
The product of any two integers is equal to the product of their GCF and LCM. That means you can find any of those four numbers by knowing the other three.

What are the negative integers of the product of two consecutive integers that equal 440?
There are no two consecutive integers, negative or positive, whose product is 440.
The product of 2 consecutive odd integers when they equal 35?

What are two consecutive even integers that equal 126?
The numbers are 62 and 64 are two consecutive integers that equal 126.
What are three consecutive numbers that equal 350?
There are no such integers.
Why does dividing the product by the GCF always give you the LCM?
In number theory, the product of two positive integers will equal the product of their GCF and LCM. Dividing that product by one of them will give you the other.
What four numbers equal 40?
There are an infinite number of groups of numbers whose sum, difference, product, quotient etc. is equal to 40 . But there are not four numbers that equal 40. In fact, there is only one number that equals 40. The number is . . . . . 40 .
